Great Service Department
In maintaining our 2020 Buick Enclave, we have used Buick GMC Watertown Ct, since our purchase in September 2019 and have always received the best on time, reliable service and friendly customer service on our visits. The staff that reviews what service I am requesting will always review for possible upcoming recommendations of service as well. The cost and approximate time of completion has always been spot on.
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.

Excellent buying experience!
My family drove two hours from RI to buy our new GMC truck at Ingersoll. The price was excellent and the service was outstanding. Kyle, the GM of the dealership greets you when you arrive and even puts the temporary plate on your vehicle. Truly an outstanding experience. 👌🏼

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

Great purchase experience
John McCoy was a great salesman! He was honest, communicated well, and applied no pressure to make a decision. This dealership was the only one on Long Island that was willing to negotiate a deal on the car I purchased. Every other dealer said that they could not lower the price of the car even $1. This is the third vehicle that I purchased or leased from this dealership and I will return when I am ready for my next vehicle.
