GMC of Watertown review
Very friendly and personable.
We were blown away at just how easy of a process it was to buy our car from this dealership. Everyone was absolutely fantastic. That includes Colleen, Matt, Kyle, Joe, Peter, and the rest. We would love to deal with them again. We are VERY pleased with the car, the service, and the general attitude of everyone there. I highly recommend them.
2025 GMC Sierra 2500 Denali review
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.

D'Addario Cadillac Buick GMC Nissan review
Great staff, nice looking cars all over the lot
Great staff, good prices, Greg (salesmen) was amazing, and Jim got me best rate possible even though he didnt have to he kept trying and got me a nice low rate. Now I hope and pray my 2014 Nissan Murano can last me as long as my Toyota highlander did (14 years) before it was totaled while parked. Will look to do business in future with Daddaro Dealer

Awesome place
I had an awesome experience with these folks. Friendly, informative, answered all of my questions. Jonathon was a joy to work with, as was Jeff. I have told all of my family what a great, stress free experience I had. If I ever have the need again it will be my go to place!

Great experience
We went to D'addario's about a used Volkswagen SUV. I worked with Ed and he was phenomenal! Never made us feel pressured and the dealership worked with us on getting into the car at the price we wanted. Would highly recommend.
