My car buying Experience
This was first time buying a car at a dealership. I like Toyota and my mother recommended Greentree Toyota in Danbury because she had bought a Camry there ten years ago. My salesman was Mike Shakro and he was very good. I was buying a used car and I gave him a price range I wanted to stay within and I told him 2016 or newer. He showed me three cars but I liked the Nissan Sentra 2016 with 20k miles on it. Max Tananbaum, one of the managers, came out to visit us and gave us below the list price. We got a Rust Proof undercarriage protection that allows us to get an additional $500 dollars if I ever trade in the car in the future. Jose Cordero was very helpful with a three year warranty that included towing and car rentals in case the car ever needed to be fixed. I was thoroughly pleased with my experience. It didn't take that long considering how busy they were and Mike the salesman even help me return my rental car by suggesting they were only a quarter mile down the road from the dealer. They have made me a loyal customer from now on.
Awsome
Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

Service is always tops Sales department the best Would recommend to anyone looking for a new, used car or service. Blasius Chevrolet is, by far, the best dealership in Connecticut
Like the truck but also disappointed
Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

We recently purchased a Cadillac and worked with Victor
We recently purchased a Cadillac and worked with Victor during the process. He made the entire experience seamless and stress-free! Victor was professional, knowledgeable, and incredibly efficient. He had everything ready for us, and we were in and out faster than we expected. It's clear he values his customers time and ensures they get exactly what they need. Highly recommend working with Victor if you're in the market for a new vehicle.
"THE" GMC Truck!
I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

Highly recommend Brewster Ford.
Highly recommend Brewster Ford. I walked in and customer service introduced me to my sales rep Tim. He was funny, knowledgeable, just a really relatable guy. He walked me through their inventory, and we began test drives. He worked with me on the price to meet my budget. We submitted the paperwork and within 48 hrs I received a call from Brian in the finance department. Another great employee, he was knowledgeable and patient. He explained every option and choice I had to make very well. I felt no pressure and picked the options that worked best for me. From the time I walked in to the day I drove away in my car was 3 days. They did everything, got me the best financing, handled my insurance, they even detailed a car I already thought was perfect. When I went to pick it up it somehow looked even better. Great group of people working at this location, if you are looking for excellent quality cars and a friendly environment you should really check out Brester Ford.
Just wondering
Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????

Found the specific, rare car for which i was searching. It was at Blasius pre owned. I had never heard of them so I took the trip from NY to see the car. The car was as advertised and I bought the car. 3 days later I went back and took delivery. Every part of the transaction was great. From the moment I walked in I was treated respectfully and everyone there is so pleasant. There were no games/nonsense just a straight, easy deal. No upsells, no hidden fees, it could not have gone smoother. I buy lots of cars and highly recommend Blasius. Special thanks to Adam Betancourt the salesman and Bobby Fernandez the GM for making this such a great experience.

On Saturday, June 7, my daughter and I had an outstanding experience at XXX Chevrolet. While my initial intent was simply to support her in purchasing her first vehicle, I ended up trading in my own car and driving away in a brand-new 2026 Equinox — while she purchased a 2025 Colorado. Both vehicles impressed us during the test drive. The safety features, interior design, storage space, and overall aesthetics sealed the deal for both of us. While comfort and safety were top priorities, what truly set this experience apart was the exceptional service we received. Steven connected us with Brian, an outstanding sales specialist who was both highly knowledgeable and incredibly personable. He built immediate rapport, listened carefully to our needs, and guided us to the right vehicles without any pressure. The process was smooth and efficient — we were both driving off the lot the same day! The dealership itself was clean, welcoming, and even treated us to a delicious lunch during our visit — a thoughtful touch that made the day feel even more special. I’ve purchased several vehicles over the years, but nothing compares to the level of service we received from Steven and Brian. I highly recommend them to anyone looking for a car-buying experience that’s professional, honest, and genuinely enjoyable. Judi and Jackie T.
