Awesome experience!
great night tonight at Performance Buick GMC! Brian Gauthier was super-friendly, informative and made the process as painless and efficient as I have ever seen, and his tag-team partner in finance James Gavenas made the finishing touches of signing the final paperwork simple and fast, while clearly explaining all options and everything I was signing. and they gave me a great deal- Brian on the vehicle and James on the protection.
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

A surprisingly pleasant experience
Best experience I've ever had with a dealership service department! Michelle and Jack picked up my car and returned it to me!! Friendly, clean, pleasant and competent. So rare these days. I would recommend them highly, especially over Freehold Buick. Freehold Buick tried to rip me off on several occasions. They lied to me and were disrespectful. I'll never go back to Freehold Buick, but look forward to working with Jim Curley Buick of Keyport in the future. Thanks so much.

We came for a Terrain, left with an Acadia. Looks way more impressive in person than online. The tri-zone climate control is a lifesaver with kids.

Showroom’s wide open, not crammed with cars. Lighting’s great, you can see everything clearly. Even the AC is perfect—not blasting in your face. I notice things like that.

If You Want the Best; This is the Dealership!
I have been with this dealership for 30 years and I have recommended this dealership to family and friends because CUSTOMER SATISFACTION is important to them. From the sales people to the service department, they are professional, courteous and everyone tries hard to make sure your experience buying a new or used car is a great one. I bought my grandson's 1st car at this dealership and he now understands why I but my cars with this dealership.

My GMC Purchase
I purchased a vehicle, a GMC Terrain, from Performance yesterday, July 30th,from this dealership. Alex, Art and Brandon were all professional, courteous and extremely helpful. It was definitely one of my best buying a car experience I have had. Thank you all for the help and effort that was put into the purchase. I live in NY and it was still painless!

Performance Buick GMC - Great Dealership & Staff
The buying experience at Performance was outstanding. Alex Kasper took care of us like family. His knowledge of the product is the best I've seen in any dealership, anywhere. He answered all of our questions and kept us informed about the status of our order at every turn. During the delivery, he took the time to demonstrate every feature of the vehicle, making us confident we could operate all of the amenities that came with the Yukon. Thanks also to Al, who made the financing and ownership paperwork process easy and efficient.
