I needed a new tire. After getting my car back I’ve noticed I pull to the right. The way they moved the tires all around which is odd to me. The rim they put the tire on has marks all over it.

We had a great experience with Mark Sweeney Buick GMC! The entire process was smooth, and everyone was friendly, professional, and helpful. We truly appreciated the excellent customer service and would highly recommend them to anyone looking for a great dealership experience. Thank you for taking such good care of us!

Nehemiah and the staff took very good care of me, I would loved to have a loaner car due to keeping my car for four days. I will always choose Mark Sweeney for my car service.

The entire experience was a good time. From coming in to the driving off. Great interactions with my salesman and your finance manager. I’ve loved the car since I took it home. I’m looking forward to the relationship that will be built over the next few years during appointments for service. Thanks for everything (except 14.4%)

Service was done timely

I am writing to share both positive feedback and serious concerns regarding our recent purchase of a 2026 Buick Envista (loaner vehicle with 1,700 miles). The Positive: The initial sales experience was excellent. The sales team was informative, low-pressure, and structured an outstanding deal with GM incentives. Because my wife does not drive on the freeway, we deeply appreciated the team delivering the vehicle directly to our home 30 miles away on the same day. The Envista itself is a fantastic vehicle that exceeded our expectations on a road trip to Chicago. The Deficiencies in Delivery and Service: Unfortunately, the post-sale experience has been the worst new-car delivery experience we have ever experienced, marked by broken promises from your service department: • Unacceptable Delivery Condition: Upon delivery, the vehicle was dirty. There was significant leaf and dust accumulation inside the engine compartment firewall, dust and grease along the rear gate rails, and a dusty interior. Furthermore, no delivery walkthrough was offered to explain the vehicle's safety features or set up wireless Apple CarPlay. We were simply handed the keys. • Urgent Component Failure & Service Resistance: The day after purchase, water drained into the passenger side rubber floor mats due to a clogged A/C drainage tube. When I called service, I was dismissively told they were booked and that "other customers have waited weeks," despite this being a brand-new purchase. • Broken Promises & Poor Communication: After a Sales Manager kindly intervened to get us a service appointment and a loaner car, your team promised they would wash and redeliver the car to our home. Neither happened. I had to chase down updates multiple times the following day. When I arrived to pick up the vehicle, the maintenance manager was "too busy" to speak with me as promised, the car was unwashed, and I was forced to drive 30 miles to retrieve it. • Missing Parts: The vehicle was delivered without a rear license plate holder. When I called, I was told I could have one just come and pick it up. I asked about mailing it and received no response so I bought a non Buick off Amazon. • We love this vehicle, but the lack of detail-oriented prep work, the dismissive service communication, and the failure to follow through on promises have severely stained our view of this dealership. We bought a new 2023 Mazda from another Sweeney dealership in town and had one of the best experiences. I did send this information to the dealership and was contacted by a great on-line person who asked me to make an appointment to come in and speak to management. I live 30 minutes from the dealer and simply was tired of going out there. I have never heard from the Sales Manager or Service Manager. I ask for nothing. My dad was a Buick guy and loved his Riviera’s. I read the new Buick provides one of the best consumer experiences for Mass Marketed Manufacturers. My experience says Buick has a long way to go. My plan at this point is to go to a local Chevy dealer for any warranty work. Love the car but the Buick experience has been beyond disappointing - - borderline incompetent and uncaring.

Everything was seamless. Great experience!

We had an outstanding experience at Mark Sweeney Buick GMC. From the very beginning, the team took the time to truly listen to our needs and wants and worked with us to find a vehicle that fit both our lifestyle and our budget. What we appreciated most was that we never felt pressured or pushed into a vehicle we didn’t want. They respected what we were looking for, worked with us on what we could comfortably afford, and made the entire process feel easy and stress-free. The Buick Enclave we chose is absolutely perfect for us, and we couldn’t be happier with our decision. A special thank you goes to Caleb, who went above and beyond to help us get the exact vehicle my wife wanted. His patience, professionalism, and willingness to do everything he could to make it happen really stood out. He made us feel like our needs mattered, not like we were just another sale. We will gladly recommend Mark Sweeney Buick GMC to everyone we know — friends, family, and even strangers! If you’re looking for a vehicle and want to work with someone who truly cares about getting you into the right one, go to Mark Sweeney Buick GMC and ask for Caleb. You won’t be disappointed!

The dash cam was not installed in the agreed upon and previously discussed location. I had a very long and in-depth conversation with the gentleman and the parts and services department about what I was looking for with the dash cam. When I went to go pick up my vehicle the first time it was like we didn't have the initial discussion at all and it had to be redone. When I went to pick up my vehicle the second time the wires hadn't been hidden and the back camera had been relocated. As I had requested, the technician failed to remove the mount from the middle of my back window and the services manager had to do that for me. Also, the first time I went to go pick up my car it smelled absolutely awful. My car did not smell that way when I dropped it off and the second time I went to pick it up when it was actually ready. The smell had dissipated but was still noticeable. Also, I had a coupon for 15% off of the dash cams which was not applied. I didn't make a big deal about it because I did receive a discount on the labor because if the work had to be redone and I had to come back a second time. Well, I appreciate that the discount had been applied, obviously I would have paid less had they honored my original coupon and provided the inconvenience discount.

Were completely determined to get me in the car I wanted and at the price I was looking for
