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.

Nice work, clean facility, courtesy and amaability, overall good job !!!bla, bla, bla, bla, bla, more and more and more bla bla bla bla blaaaaa

We have worked through Frampton Walker for at least 5 GMC vehicles. He is our first call every time we need a new car or have an issue that needs to be addressed because of his professionalism, attention to detail, and he solves our problem.

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!

My experience at Greenbrook Chevrolet was absolutely amazing. They made the car buying experience so simple and were very clear the whole time. I would highly recommend those looking for a new Chevrolet to come in and ask for Yannie!

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.

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.

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.
