"We had the best car buying experience at Vachon. We were lucky to work with Tom and Jeff, who were wonderful, but everyone we met at the dealership was so kind to us and our children. We got a great vehicle at a fair price and never felt like we were being upsold. Tom and Jeff are good, honest sales guys, which hasn’t typically been our car buying experience (unfortunately). We live an hour away from this dealership and wouldn’t hesitate to recommend them to anyone, they are worth the drive! We hope to bring our car here for service as well, just given how great our experience was."
"I had the pleasure of working with Sean and Geoff, who both made my first car buying experience a great one. They were very transparent, fair, and reasonable. Sean took the time to answer all my questions and show me how to use all of the car features prior to me leaving the dealership. I appreciate their willingness to work with me. I would highly recommend Vachon to other car buyers."
"I had been looking for a 2024 Buick Envista ST with specific features for a very long time, but after finding Vachon, I found the perfect car for me! I worked with Tom who was incredible! He walked me through everything, never pressured me, and helped me get a great deal! As I am out of state, I really appreciated how nice and helpful everyone was. Geoff and Ashley were also great, personable, and kind. I look forward to coming back in for any maintenance when I am in the area. I would absolutely buy another vehicle here in the future and recommend anyone to buy a vehicle here for the value and service they provided!"
"Tom, Geoff and Ashley were great to work with on the purchase of my new GMC truck! Tom took the time to test drive multiple new trucks and point out their features. Geoff was great to deal with and gave me a great price on my trade and on the new truck. Paperwork was handled by Ashley who had everything prepared ahead of my appointment. There were no extra charges like at some other dealers. Very transparent and professional! Vachon had the best selection of new GMC trucks and were great to work with. I would definitely recommend them over other dealers in the area for price, professionalism and selection! Thanks for a 5 star experience! Love the truck."
"Here we are, writing a good review for the one industry I never thought would deserve it. The team over at Vachon in Old Saybrook is far beyond remarkable. From Sean at the sales desk all the way up to the partner I met, Stew, these guys clearly value community relations over profit margins. If you are in the market for a new vehicle, be sure to trust this team to make it an unforgettable experience."
