Hudson Cadillac Buick GMC review
Hudson Buick - Poughkeepsie NY
In 2021, I purchased my 3rd Buick Encore from Hudson. They made the process so easy. I admit during this period of COVID was an issue and the supply of new cars was limited. Thankfully the dealer did have an Encore that was in my price range. It wasn't the color I wanted but beggars can't be choosers during this period. They worked with me to fit my budget. In fact, my lease fee was less than my previous vehicle. So I was quite happy.

I became part of the Romeo Buick Chevy family back in
I became part of the Romeo Buick Chevy family back in October 2015, and since then, I’ve purchased three new vehicles. Each experience was guided by Matt and Steve, who have always been helpful, knowledgeable, and trustworthy. I have great confidence in both the sales and maintenance teams, they truly make this a friendly and welcoming place. I’ll definitely continue to recommend Romeo Buick Chevy to my family and friends!

Colandrea Buick GMC, Inc. review
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
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.
