Worked with both MATTS they came to what I wanted for a payment. It was all done without going to dealership and that saved a lot of time. They were very professional, helpful and courteous though the whole process. The finance dept was smooth and explained all the paperwork for a fast transaction. I leased three vehicles from the new owners and will go back for my fourth. THANKS FOR ALL YOUR GREAT HELP.

Exceptional Service at Rochester Toyota In my opinion,
Exceptional Service at Rochester Toyota In my opinion, the heart of the dealership resides in the service area. I can honestly state that I have never received the outstanding level of service provided by Rochester Toyota. Consistent follow-up and timely response with the service department were above and beyond expectations. I would like to sincerely thank Jeff Stevens and Tyler Lessard for their team effort and conscientious handling of my service needs. Their dedication and attention to detail have made every visit a pleasant experience. I highly recommend Rochester Toyota if you are in the market for a new or used vehicle. Their exceptional service and commitment to customer satisfaction make them a top choice in the automotive industry. Check them out, you won't be disappointed.

I recently bought a truck at Auto Mart in Derry, NH and found the process to be easy and seamless. Chris, the salesman, was knowledgeable, patient, and helpful. He answered all my questions and was very professional. He also made sure to give me a card in case I have any questions or needs regarding the truck in the future. I would definitely go back to him, as well as share his name with friends and family!
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

My experience was fantastic.
My experience was fantastic. I've gone to Kris Dumont for my last 3 cars now, and I continue to go back to Banks because he is there. Buying a new car was fast and convenient for my schedule, and Kris goes above and beyond to ensure a smooth experience.

Matt at Tim's truck capital was awesome to work with. He answered all my questions and was willing to work with me being an out of state purchase. I found a truck in state instead, but I'd definitely work with Matt again if I need another work truck. Great business with a great selection of trucks

Thumbs up to Casey!
I recently had the experience of working with Casey to purchase a new car at Rochester VW. I have bought many new cars and I would like to say that this was the easiest purchase I have ever had. Casey did everything she could to make sure I got the car I wanted. I will definitely refer her to friends when they are looking to purchase a new car. Thank you Casey for being the BEST sales person ever!!
