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.

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!

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.

Chris was the best to deal with; quick and to the point would definitely buy another vehicle from him. Young boy but knows his profession.

Peter was the best. I have over 50 automobile purchases in my life time. And this was the easiest and best one yet. Thanks again

I had a really good time buying my new car with Bomnin. Jonathan C did really good job.

Very Fast Service. In by 745 am, diagnosed as a fuel pump by 930 am done by 230 pm. I made the Monday appointment on Friday afternoon !

I was finishing a purchase of a new AT4 b 2500HD I know that I can be a bit difficult, but Phil the Sales Rep and Amanda were just awesome to work with and handled every concern I had. Thank you both

Every time I get a service done the customer service experience is impeccable. Although I travel 45 mins out it is worth it because I do not get the same experience with GMC service companies closer to home. Keep up the great work and the staff is always warm and friendly.

George Gregory got us into the right car?.the process was painless. George was friendly and professional. This is our third car with SL and we?ll be back for our fourth.

Excellent service with my GMC Yukon Denali - very attentive and took me in without an appointment.

I recently purchased a used certified GMC Sierra from Sawyer Lyons.The sales and service experience has been outstanding.My salesman,Harold,and George with the paper work were great. Service and parts were also great. This is a fantastic dealership to do business. I highly recommend this dealership.

Jonathan Cadme made my car buying experience easy. He was nice and transparent. I will recommend him to friends and family.

I recently had the pleasure of trading in and purchasing my 2nd vehicle in 3 years from George Gregory at Sawyer Lyons GMC. Every time I visit this dealership (for service or sales), I feel welcomed and valued. George, who has always been both friendly and professional, always takes the time to say hello and that leaves a lasting impression on customers During the sales process, he has never pressured me into making a decision but instead encouraged me to take my time and ask questions. What really stood out, though, was his commitment to ensuring I got the best deal possible. He worked with the finance team to offer competitive pricing and tailored options that fit my budget. Throughout the negotiation, he was transparent, honest, and made sure I was comfortable with every step. Because of my experience with George, I feel confident in my purchase, not just because of the great car I was driving off with, but because of the exceptional service I received. It's rare to find a car salesman who genuinely prioritizes customer satisfaction over making a sale, but this one certainly did. If you're in the market for a new vehicle, I highly recommend working with him—his professionalism and customer-first attitude made all the difference.

Funny moment: when I picked up the Acadia it was shiny in the showroom, but once you drive out there’s dirt and salt. The delivery guy gave me a couple of local car wash tips and even suggested where they don’t overcharge for touchless. You can tell he’s local, not a textbook seller.
