Very kind people.

Andrea was so helpful and understanding through the entire process!

Very efficiently run service department.

I ordered a step kit for my GMC Canyon elevation from their parts department. I called a week an half later to find the part had came in and no called me to let me know the part had arrived. Made the part to have it put on only to find it was the wrong kit for my truck. This time a called the service department see if the kit had arrived after some time had passed only find no had called them to let them know the step kit had arrived. Set appointment for 7/16/25 for 7:30 am, arrived at appointed time. I received a call about 4 pm telling me it was the wrong kit for my truck. They are so sorry they will reorder and get the right kit in. I went to the parts department and ask for my money back. Then I am told they have to send me check, l informed the person you took the money from my credit card but it back on my credit card. The company can only refund in a check. We are living in the electronic age if you can take it from my credit card you can put it back. If this is how GMC does business than I need to trade this truck in for a Ford with running boards installed. I sure I get a good deal on a 2021 GMC with 9000 miles

No pressure sales and easy financing

Fast service great communication throughout service

I valued the quick service and friendliness of the team at the office! Very considerate and accommodating! Customers were in and out — a reflection of efficient service, but also a reflection of trusted service!

Dropped my truck off at the dealer ship for some diagnostics. Unfortunately I had misread the date, wrong Tuesday. I was contacted early and since I could get by without it for a few days, the service agent stated that they would try and fit it in within next couple days. Later the next day, he contacted my again and had done the diagnostics. I was very surprised it was done so quickly and was able to pick up my truck. I was very pleased I didn't have to wait til the next week. So far Union Park GMC has been doing right by me and I haven't found anything to complain about. I can definitely recommend them as a reliable service department.

Everything was fine

Dennis handled every issue and then some to my great satisfaction.

Service advisors took care of my SUV problem.

I was waited on promptly and offered a free ride thru Lyft to and from work. The work was done in a few hours and I was notified by phone that it was ready. No issues with the service work.

Good and quic

Dennis was great to work with!

Nothing to say, Wesley was very courtesy.

Team was great at scheduling and servicing the problem.

No pressure very friendly

Dennis was great in getting the job done quickly!

Excellent dealership A bunch of great people:handled issues professionally (new car had issues) Thanks To Christopher Meeks great customer care sales team work I was informed every steps Thank You All :Highly recommended:

Gregory, rep was VERY helpful. Directed me to comfortable waiting room, took my car keys and all needed car work was done. He finalized paperwork and I was good to go!

The only complaint I had is, they didn’t have a loaner car for me to have until they were able to fix my car, but I didn’t have the financial means to get my car fixed at their price

The communication was great and everything was done in a timely manner.

Everyone I dealt with was very nice. I would recommend Union Park to friends and family.

I was greeted by being told that my appointment wasn’t in their system, even though I made it through the MYGMC app. Proceeded to tell me next time call. After that, I told him I made my oil change & 7500 mileage check. They told me it costs generally $91, but today is free since it’s my first visit with new car. I let them know that my Acadia’s brake warning light & traction system has also turned on, and they responded complacent. The waiting room was not very welcoming, and I felt uncomfortable waiting with the men at the front computers so I went into BMW to wait. When I picked up vehicle, I asked about the brake light, and they told me i needed to make another appt bc there wasn’t any diagnostic time that day. They said I’d have to come back with a new appointment, even though my brake light was on. I took it to the GMC that I bought from in NJ, and they let me know that I couldn’t drive my car out since the brake light is on, and sent me home with a complementary vehicle. I was upset to hear that it was not safe for me to drive, and the initial GMC in DE told me to make another appt bc appointment to come back.

Quick, quality service. Amazing service.

Really appreciated the fast professional service and the waiver of some of the fees too!

Dennis could not have been more customer oriented. It’s difficult to find these days.

Sales person and staff very helpful and made purchasing a breeze.

Took two hours to do an oil/filter change with a tire rotate, I thought was a little bit long but then i was not back in the work area to see what was going on with other work. I appreciate the multipoint service checks that’s performed on the vehicle and recommendation of other services that could be performed on the vehicle. The service advisor kept me informed on the progress of my vehicle.

Gregory is always helpful, pleasant attitude and funny sense of humor ☺️

Great service

Waited next door at BMW and my truck was finished quite quickly

I had a small emergency situation and needed help immediately. Even though it was a kind of crazy request on my part Greg at Union Park Buick was incredibly accommodating. He went above and beyond to get my car serviced for me in my timeframe. Then he was kind enough to give me updates throughout the process so I could coordinate everything with my schedule. An awesome experience! I always get my car serviced there but this was the first time I ever needed things done in a specific way. Again Greg was great. Highly recommended!

This was a great experience. Jim made the process seamless and pain free.

My car sa parked at your dealership for 3 hours and no service was performed. I received a call from your dealership (Betty) and she said that they had received the wrong part for my car and they were able to service my car. I asked her why my car sat for 3 hours (in the same space I parked it in) without anyone realizing that they had the wrong part? She responded, we had 25 appointments today. I think it was very unprofessional and ridiculous that my car sat for 3 hours (without anyone touching my car, when the service would have taken 3-4 hours to complete) before someone realized that you all had the wrong part. And I had an appointment that I made the week before. So, an entire day wasted (my time is just as important as anyone else's) without any service being done to my car. I was very upset!

Great service representative

Quick and timely maintenance. Dropped Truck off and it was ready for pickup early.

I brought my car into the dealership. Although the staff was pleasant nothing was done to my car in 2 days. I called and they said they needed to order a part that would take a week. I brought my car back after a week and was told it would be done in a day. I was then called and was told the wrong part was ordered. I picked up my car because of the inconvenience and the lack of knowledge of the staff.

I called to make an appointment for oil change and tire rotation Dennis was very courteous on the phone and was able to make an appointment for that Monday it was a Friday when I called . When I arrived Greg helped me who also was very courteous and helpful I didn’t have to wait long for my Buick Envision to be done. I highly recommend Union Park for your service needs.

Very friendly and helpful explaining all of the new tech.

It was a long process but communication was good

fast and friendly

Very efficient with Wayne (checking in) and Brandon (checking out)

Good

friendly, courteous

I was told by Beth that I could drop off my car at 7 am ( on my day off) and my car would be done by noon. She went on to say how great the technicians have been doing. Noon rolled around and no call . I texted and called the number I was provided with no return call or text. 3 pm rolls around and a service technician said my car was not looked at and they would need the car another day. Totally unacceptable to get a promise by noon and now the car was not looked at all. I asked to speak with Mike that is whose name was on the manager voicemail. I was told he was no longer there and I would need to speak to Jeremy. He got on the phone after yelling my concern to him and telling him I was going to contact the owners, he then said he would give me a loaner until they could look at the car. I got the loaner. The next day at 10 am I got a call from Jeremy stating they couldn’t fix the problem. This isn’t the first bad encounter I had with them. What really made me upset was when I told him I. Was going to contact the owners he said no worries. I placed a call to him and the service advisor line since then and no call back. Horrible service.

Work was completed well before the estimated time. That was a good thing for me.

Quick and easy.

Great experience from initial contact online to test drive to driving home in my new car. Thank you, Javier!

Great customer service I was treated well. Thanks

We requested to have service completed for our Acadia that would pair a remote back up with the car. Communication was not clear that the dealership would need both remotes at the time of the repair, so when we got the car back the malfunctioning remote is now paired with the car and working, however the originally working remote is now un-paired. Now we have another appointment and are told we will be charged for this work to be corrected, when the communication was not clearly made that the dealership would need both remotes to properly complete the work. I do not think it is right that we will be inconvenienced a second time to fix this problem and we will be charged on top of that—all due to unclear communication from the dealership.

This dealership is run like no other. The staff is knowledgeable and very attentive to their cllients. They are patient, kind, and so willing to assist their senior citizen buyers!! No small feat! From the general Manager, Gregory Lashbrook, to the sales force, Andrea Gambagorta, and finance, the experience was seamless. I so appreciated the follow up two days after we purchased. I will highly recommend thos looking for a new car to check out this dealership. Thank you to all.

Professional team, fast , quick and clean with the service.

When I scheduled my appointment, I had requested that I can wait for the vehicle. The scheduler said yes. This is the second time I had asked to wait. Thank s to my service rep. He got it done while I waited. I had an oil change and tire rotation.

Everyone was helpful.

Great experience with the team in service at Union Park.

1: I booked an appt on Wednesday 2/25 for Friday 2/27. When I arrived for my appt I was told my appt was cancelled for unknown reasons. 2: I was told if I could come back Monday 3/2 they would still honor my $25 discount that would have expired on 2/28 & accommodate me with an Uber back home so that I do not have to sit and wait in the lobby. When I arrived for my rescheduled appt I was then told they were unable to send me home in an uber after coming only prepared to drop my car off. I was left to wait for a service I was told I would NOT have to sit and wait for. 3: After services were complete the same guy who told me he would honor my coupon then told me he could not apply it until I had to remind him of the conversation we had previously. Overall I was not happy with the my experience

Super friendly staff, easy to contact, very

When I dropped my car off the customer service was awesome. My car was done in a timely manner. Overall I was very satisfied. The only thing that i wish that we get a complimentary car wash!!!!

The entire process was easy from dropping off my car, to receiving my loaner, and picking up my car. Greg and Beth are great!

Friendly and prompt service

Brandon helped me with my appointment for service, Thank You! Great Service.

Took vehicle in for recall, great service, prompt communication via email and phone call. Associates were very friendly. Loved the Lyft perk!

Javier, Chris and Randy was absolutely amazing. They went above and beyond for me. From the beginning of the process to the end. I have to especially appreciate and so grateful for Chris. I may have been a pain during the process because this is my very first brand new car but Chris was so patience with me and made sure that I got the car that I was obsessed with.

Great client focused and professional. Always take care of what is needed and not more for services not required. Greg is a wonderful service advisor who listens and responds with information and care. Have used Union Park service for years!

Alfonso make possible the purchase of my new vehicle.

My only complaint is that it took over an hour and a half to complete

Jim and Randy were both super helpful and made the process easy.

1. Did not honor coupon for routine maintenance. 2, Did not review paperwork when job completed. 3. Did not provide inspection report. 4. Did not inform of 2% credit card surcharge. Did not return 4 phone calls and one text message over 3/12 & 3/13.

Very quick excellent customer service ????

Wonderful

My experience was okay overall; however, the wait time was much longer than expected. The waiting area was cold, and the employees were not very informative when it came to recommendations for my car.

Brandon V. was very kind and professional and his colleague sitting to his left was very caring.

The people at Union Park GMC Buick are the best! Cheerful, professional, knowledgeable, and friendly. I had a great car purchasing experience!

Everything was excellent service, communication and customer service

Everything went very smoothly.

One of the best vehicle purchases ever. Union Park found the vehicle I needed and changed it to my liking. Very easy to deal with. Good price. Great staff!

Great group of guys really enjoyed the environment they provide!!

VERY GOOD TEAM

This rating is skewed due to the loaner car issue. (see further in the review) While the Asst Service mgr. - Brandon did his best to help and was very nice, (5 Stars) the overall experience was not great at all. I had a Wednesday appointment and dropped the car off a day earlier (Tuesday). I advised them of the electrical issue and adamantly expressed to them it was not a key fob issue (which is what they and another previous GMC service wanted to go to first.) I knew it was going to take a few days to figure out the problem, but what I did not expect was them getting the car back on the following Friday (9 days later not including the weekend). The main problem with that was THEY HAVE NO LOANER CARS WHILE YOURS IS BEING WORKED ON!!!!!! unless you have factory warranty and only 9 cars available. This must be a Delaware/Maryland thing as I've always been given the option of a loaner car in NJ from the dealerships. This was even for oil changes etc if they could not get to my car early. Even after the 9 days the issue was not fixed, and I still ended up with a bill. Brandon did work with me on the bill but I would like to have the electrical issue fixed. Now I still need to come back but I advised them if I can't get a loaner car while it's being worked on I would have to wait for another month to bring by. My last option will be to go all the way back to NJ where they offer and have a well-stocked amount of loaner cars. **** This service was at least 10 times better than the last GMC dealership (I.G. Burton group/Anchor Buick GMC) in Elkton, MD who had my car for 4 days and said the electrical issue was fixed by " putting a new battery in the key fob". 4 days and that's the answer I got from them. Yes, I put their name out there.

I came in for service. I was in and out quickly. I did spend more money than what I wanted to. Job well done

Experience was good. They really tried to get my family exactly what we wanted. Although they couldn’t I still left very happy with my vehicle.

My team member Dennis went above and beyond to make sur my vehicle was taken care of.

Satisfactory

Each and every employee was knowledgeable, friendly, helpful, and patient. Would definitely return to your dealership

It was great. The employees were super helpful and the follow up was great. They let me know what was wrong with my car and gave me a detailed time line of when it would be finished. They called to let me know when the parts came in. Just an overall great experience.

Excellent service on my GMC terrain thank you Jack

Great Experience! Fast process!

This service group always takes good care of my vehicle and is professional and courteous with me as a repeat customer. Would highly recommend this service group to anyone.

I went in just to look at vehicles and sales associate Jim VanDyke made me feel so relaxed and confident that I but a new vehicle that day. Both him and Randy in finance were very understanding that I was nervous about such a large purchase that they encouraged the whole process with a FaceTime call with my daughter.

Good service

I recently had car maintenance done at Buick GMC, and I can't recommend them enough! Wesley, the service advisor, was outstanding. He was professional, efficient, and incredibly resourceful. Wesley took the time to answer all my questions thoroughly and offered helpful recommendations tailored to my vehicle's needs. His knowledge and expertise made the experience smooth and reassuring. I wouldn't hesitate to work with him again in the future. If you're looking for quality service and a knowledgeable staff, definitely check them out!

I had a few problems with my 2024 envision and 2023 Terrain along with my Apps going down. Your dealership was very helpful and solved my problems in a very short time. Thank you

Nice

Very friendly staff

Randal & Sam was amazing with their politeness and customer service skills.. I 10/10 recommend dealing with these two each time for any reason or concern you may need.. They also put in time & effort n making the best decisions for your financial future

Dealing with Alfonso was very easy, told him what I was looking for found what I was looking for had it delivered the next day for a test drive. Couldn't ask for a smoother transaction.

They are very professional and they take the time out to explain what's going on and what's the next step. I'm very satisfied and feeling very comfortable with the services

Very friendly staff, fast service.

Very efficient with Wayne (checking in) and Brandon (checking out)

A simple oil change took 4 1/2 hrs. Took it on at my scheduled appointment 7:20. Told them please pick me up around noon...they said "no problem". Checked car status at 11:15 and had not even been looked at. I was told they were short handed... This is the 2nd time within 3 months of needing their service I was told that. Why are they scheduling so many in one day if they only have 7 bays or not enough service techs? I have been a loyal customer with union park in both buying cars there and using their service but I feel if my car wasn't still under warranty, I would go elsewhere.

My car was finished earlier than expected. Thank you!!

I scheduled a service recall appointment approximately 2 week in advance. Dropped the vehicle off that morning and took a Lyft ride to work. About 30 minutes later I received a call saying they couldn't do the work because they were missing some material.

Everyone was helpful and friendly

It was great

Brandon was wonderful so accommodating

I worked with Jim at Union Park GMC. He was super helpful, responsive and knowledgeable. I had a great experience and would work with Jim again. Highly recommend

Thank you for a great experience.

Great experience all round.

Great service

Waited on me right away and took care of my need

fast and friendly

Beth and Greg are awesome to work with.

Great Job Union Park Team

Came in for my second free oil change after purchasing my vehicle with this dealership group. Needed 2 brake pads in addition to that. Somehow replacing 2 brake pads took a full day and the cost was nearly double of what I would have expected. Even the clerk checking me out noted that I am not the first person to be confused by the exuberant cost. I guess I will stick to going to my usual service center now that my free oil changes are up. The service center itself is clean, and the work seems to be done properly. It’s the slowness and exuberance in cost that will prevent me from coming back

Good service Good service reps

They did not meet my expectations. When booking I asked for an oil change and the recommended service for the vehicle with 100,000 miles but they only did the oil change and said it needs more service but I would have to schedule that for another time.

Great service, Brandon was very professional and great to work with!

I was very pleased and highly satisfied with the Best Sales Lady, Ms Andrea, she is so friendly, patient and very helpful.. Andrea made sure I was happy with the deal, thank you again Ms Andrea. I appreciate you..

If i could rate this Service Dept a ZERO STAR I would! My vehicle was kept around this place 10 days. First i was to pay over $300 for extra time 2.5 hrs the tech needed, because my extended warranty that I've purchased alloted 5.5 and not 5.0hrs. Called Assurant myself and was told different(straightened that) NO FEE FOR ME after i told the Service Advisor(BETH), then the parts weren't in(had to wait). After that came the wait time again! Then here comes the I need a Battery! NO THANK YOU, NEVER AGAIN! The 3B"s definitely will hear of this as it is so much more to be added to this horrible Service Dept!

I was pleased that the dealership kept my speaker parts on hand after several missed appointments. I was also pleased that they provided a Lyft to and from work to get my vehicle. I would like for this car to have a routine maintenance schedule so that I can rest assured that my vehicle is running at optimal. Just telling me everything is fine is not reassuring!!

My sales rep was awesome. He listened to details of what I wanted, he found the car i was searching for and he was extremely patient with my schedule. The whole process from beginning to end was within a great time frame and I will definitely refer my friends and family to him

Fast clean and on time service

Excellent customer service. Very accommodating and easy to work with.

Service advisors are always friendly and helpful. Service was done promptly. No unnecessary maintenance pushed by advisors. Pleasant experience.

Gary help a great deal

Randy Day was as professional as they come. Javier was also very knowledgeable and welcoming. We even had time with the GM, who was a well versed gentleman.

Everything is perfect.

Everything went great! From scheduling the appt, the estimated time for service was accurate and the service was completed on time. First time customer is very satisfied.

CHRIS MEEKS, GREG AND RANDY MADE THE EXPERIENCE PAINLESS... ONE TRIP AND DROVE OFF WITH THE TRUCK I ORDERED. WHEN ITS TIME FOR MY NEXT TRUCK, I'LL BE BACK. DAVE P.

Great customer service

everything went well with the exception of you not having the tire monitoring stems to replace my TPS system, would’ve known that when we made the appointment they should’ve checked stock so now I have to come back.

pleasant and helpful

Our last experience buying a car was during COVID and a hard one. This one was much better, faster and more enjoyable

Very professional and friendly. Car was done earlier then promised. Check-in and check out was easy and fast.

Great people

Everyone was cordial and knew what they were doing.

Very pleased with the service I received , thorough, timely a very big Thank you to Wesley Haynes and Gregory

Great experience

Sam Williams was my salesperson and Randall Day the Business Manager. they worked together to get me a fair deal on my 2026 and handled all aspects of the sale with a positive, caring and professional manner. I would clearly refer Sam to family and friends and think Randy is one in a Million. As a retired LT Col in the Air Force, I appreciate Randy's commitment to our country and his service. The Union Park Dealership will certainly have my repeat business.

Great on time service that a person can appreciate in this day of Age

Brandon was very courteous and professional. He set expectations for how long the service would take and answered other questions regarding the vehicle and service history.

Very kind and attentive to customers.

Everything was explained to me. I did not feel push into getting unnecessary things done.

My experience was good, even when parts company were behind Mrs.Elizabeth made my experience great in was very positive in helped out in way she could I would definitely come back there in hopefully she represented me if I ever have too come back

Everyone was very nice and helpful and caring

Beth was very friendly and professional. The lack of parking made the check in process confusing, but Beth was very helpful.

I valued the quick service and friendliness of the team at the office! Very considerate and accommodating! Customers were in and out — a reflection of efficient service, but also a reflection of trusted service!

Fast courteous service couldn't ask for any better

I dropped the car off at 9am for an oil change and tire rotation and it wasn't ready for pick up until 4pm. The next day I was driving the car and noticed a smell and smoke coming from under the hood. When I got home and opened the hood, the engine oil cap was never put back on and oil had spewed all over the engine. I texted the service department with pictures but never heard back.

I made my appt. for a Thursday morning. I was told they would not be able to look at my car until at least Friday morning. I was also told that rental cars were not an option for me, even though I bought my car brand new, and it is still under warranty, because they were all out. With being a part of a larger dealership group, you would think they would have a deal with a company like Enterprise or something that would allow them to keep that as an option when the courtesy cars are gone.

The agent went over everything to make sure I understood what was being done.
