Hudson Buick Dealer, Poughkeepsie
I needed a new battery for my car which was still under warranty. I called the dealership where I purchased it but unfortunately they couldn?t fit me in for three days. I called Hudson Buick and they told me to bring the car over, they drop me off at the mall for a little while came and picked me up on my car was done. Great experience.

I bought two cars from Mike Barrows.
I bought two cars from Mike Barrows. Mike's salesmanship goes unmatched. He did not pressure us at any point and was always willing to do his best on a price for us. The transaction was quick, easy and smooth. Just to top it all off Mike donates $50 dollars for every car he sells to united for the troops and having two grandparents that served this really blew me away. Thanks Big Mike!

Painless, fast, and rewarding experience ever!!!
I walked in with something very specific in mind. Even though I didn?t get the car I built online Colandrea was able to offer me the next best possible thing. I?m picky but their associate read my mind and was attentive to what I wanted. I looked at just one car and fell in love with it. Took it for a test drive and made the deal. The longest part of the process was trying to see which of the approval offers best fit me. They fought to stay within my budget. They found me the lowest payment option possible. I was in an out of there in less than 3 hours and returned the next day for my vehicle. Painless!!! This is my NEW dealership! Thanks to Floyd and Dan!

Although I did not purchase a car, I would highly recommend them based on the interaction I had through email with Carissa S. She was very responsive, answered all my questions and got back to me quickly. I definitely would purchase a car from them in the future.

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.
