Used GMC cars for sale near Cos Cob, CT

I found a great car here at a fair price. The vehicle itself is fantastic. The only reason I'm giving 4 stars is that I felt a little pressured towards the end to add some extras I wasn't really interested in. However, I stood my ground, and they respected that. Overall, a good purchase.

I have enjoyed my vehicle. It is comfortable and drives very well. I like the color also. It is very roomy, takes off fast and the safety features are very beneficial.

Dominique is an excellent salespersons. He is patient and knowledgeable and the whole process was done without pressure. I Will definitely be going back to Bright Bay Lincoln in the future, and I will recommend this dealership to my colleagues.

The Yukon checked all of my needs, I have plenty of room for my children and my Great Danes. I enjoy driving the Yukon and how it handles, overall love this vehicle!

Samuel nos dio un buen servicio. nos vamos felices con nuestro carro. muchas grasias magic

This Yukon has all the bells and whistles. It is a joy to drive, the drivers area is like a cockpit with everything at your fingertips.

Pleasantly surprised that my car was repaired so quickly. Very nice and helpful Service Advisor Stan. I was quite shocked when he called to say it was ready.

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

Overall Great Experience from start to finish. Elder and Ralphie communicated with us every step of the way and made the process of buying our car seamlessly. They both were friendly and professional. I would definitely recommend Stream Auto outlet in Islip if you’re looking for a great selection and team. Mark & Jenny

I had an exceptional experience at Minchin GMC in Stamford, CT thanks to Chris. From the moment I walked in, they were friendly, professional, and truly attentive to my needs. Chris took the time to understand what I was looking for in a car and guided me through the entire process with patience and care. They answered all my questions thoroughly and helped me find the perfect vehicle that suited my preferences and budget. The entire purchasing process was smooth, and I never felt rushed or pressured. I highly recommend Chris if you're looking for top-notch service and an easy, stress-free car-buying experience. Thank you again, Chris, for your outstanding help!

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Jay and his father were incredibly accommodating and made the process easy. Gave a fair value immediately without having to negotiate for my trade-in. Car came with a full set of winter tires, rims included, that was thrown in for free in addition to the all-season tires. When I showed up to pick up my new car, it was in pristine condition with a full tank of gas. Any request that I made, Jay and his team delivered. If you are in the market for a new car or are looking to sell yours for cash, you should give Westchester Auto Exchange a chance to earn your business.

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

Always reliable and outstanding customer service. Waiting area well stocked and comfortable. Staff friendly and informative, attentive to details and future needs. Service department used modern diagnostic equipment that can be reviewed while waiting

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!

Michael Rose helped me remotely to buy an F350. Quick replies, good follow ups, and honest. When I arrived to purchase in person everything was lined up and it only took an hour. I buy a lot of vehicles for my business and was happy with how fast Michael and financing employee Brian made it happen. Highly recommend these two for their professionalism and straightforward approach.

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.

My salesman Bernie makes car buying easy. He’s very knowledgeable and a credit to the dealership. Celine the finance person is very good and also a credit to the dealership. I will have no problem recommending Blasius !

Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

Bought a Toyota Corolla for my daughter, and we couldn’t be happier! The process was smooth, and the car is perfect for her. Great experience all around!

I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

Every thing was smooth except for a couple of minor Issues that can be resolved, Thanks Guys

We always have a great experience at this dealership! Bobby has consistently taken amazing care of us over the years, and we couldn’t be more grateful. Sally Morshed and Seth have also been exceptional throughout every step of the process—professional, attentive, and genuinely helpful. What really sets this group apart is their honesty and integrity. They’re not just trying to sell us something—they truly care about doing what’s right, even in today’s world where costs are rising everywhere. We sincerely appreciate the time, effort, and genuine care they put into every visit. A fantastic team all around!

I love my Acadia Denali. It is fully loaded with anything you can think of.I love the V6 engine and how smooth it drives and rides

The buying process was easy. I came in and ordered my silverado 1500. The bad part wasn't the dealers fault but I placed the order on December 24, 2024. It came in April 28th , 2025. That was over a 4 month wait. That is way too long .

This truck is great if your not trying to haul 10k lbs. For every day use it's great on gas and I fit everything I need in the bed.

I worked with Daniel Brendler. Because of his knowledge, experience, and easy going personality, I will definitely come back to him when I am ready to purchase a vehicle.

I fell in love with my GMC Terrain when I test drove it and have not lost that loving feeling! I have received tons of compliments on it.

Ronny Terraferma was amazing. Treated myself and my daughter like family. He was honest and professional throughout the entire process I will definitely will return for my next car!

Valentina and all of the staff at Hillside Toyota were exceptional in helping me purchase my brand new 2025 Toyota Prius Plug-in Electric Vehicle. Valentina, George (who spoke to me in my native Greek), Salvatore, and all the gentlemen at the manager’s desk were so pleasant, helpful, and attentive. When I first visited, Valentina asked me if I had a favorite color. Then she asked me to choose my 3 preferred colors in order of preference. By the next day, Valentina called and said that Hillside had my first choice of color, the Cutting Edge, a beautiful smooth and elegant silver. Valentina also did an amazing job in handling the many complex details in leasing my Prius for the first time. She is a genius in technology, efficiency, resourcefulness in her ability to do what’s needed to meet my needs. Thank you everyone at Hillside Toyota💕💕💕.

Really nice to drive! Extremely comfortable almost like a recliner!! Sturdy and solid! GM had issues with certain years for oil consumption is the only issue. I understand GM is making good on it now! As long as it’s checked over otherwise these are extremely nice cars!!

Our experience at BMW of Freeport was great! We are first time customers and our experience couldn't have been better! Marleny was wonderful! She was with us through the process from inquiring about our car until we drove off the lot! She knows her vehicles! Everyone at BMW Freeport made this an enjoyable experience. I would recommend Marleny and BMW of Freeport!

Love this Denali 2019 Acadia. Bought in 2018 with a large Houston Dealer Discount (22%).
