Used Buick cars for sale near Cos Cob, CT under $1,000,000

I have driven my 2025 Buick Enclave Sport Touring almost 9k miles and I am beyond happy with the car. The car is very smooth, comfortable, beautiful and economical. I do both city and freeway driving and so far, my MPG average is over 29 miles, getting about 580+ miles to a tank of gas! My 2025 Enclave drives so much better than the SUV I used to drive that had a V-6 engine and gets over 10 miles more per gallon of gas, on average. I have more than enough room when transporting family members and/or my (3) dogs. Everyone enjoys being a passenger in my Enclave.

I have owned this car for almost 2 yrs & it’s been very reliable & comfortable especially on long trips I would definitely buy again very happy with it.

I’ve had my 2019 Buick Envision since January of this year (2023). We were traveling from GA to MS today and for the first time ever after hitting a bump two different times (a couple hours apart) our vehicle started vibrating and shaking terribly. Very concerning.

I had a very good experience here and everyone was so helpful and pleasant and made buying a car very easy and I was able to leave happy

Great vehicle with room for seven and plenty of cargo space. A great motorhome TOAD thru model year 2017. Powerful V-6 engine and smooth shifting transmission.

2nd car I have purchased from Mike at Kar Connection. 1st car was good that 3 years later I went back and purchased a 2nd. They helped with financial stuff as I am not one to go to the bank. Just not my thing. I'll be back I'm sure for a 3rd.

Bought it used in May 2022. It's a 2016 Buick Enclave awd Tucson Edition (displayed as leather). It's a nice car, was around $28,000 from carmax with 70k miles. It's first problem occurred in June 2025 when the ac stopped working, it got fixed. Only major problem was at 105k miles when the transmission had trouble. Reason why was because the dealer said it had the 4,500 lb tow package, but it was missing a crucial part needed to tow. Transmission was fixed, and car still runs fine to this day at 108k miles. 3.6L V6 288 horsepower.

My experience with the sales representative and the other Major world team was very professional. The team makes you feel welcome, comfortable and excited about your purchase

Was looking for safety and security in a suv Comfort for neck and back were important this particular model goes above and beyond. Ride is smooth and quiet with what engine doesn't have in speed it has in hidden torque in motor. Black on black with black grill and rims with crushed glass in the paint, so many compliments especially how masculine looking the vehicle is The dealership Garber of Fort pierce has been amazing from sales to service to accessories Best purchase I've made in years highly recommended

Helpful. Not sure why you need a fifteen word minimum. This should get me over the limit.

Great to deal with from start to finish. Listened to our concerns and repaired any and all items. Quick and professional.

I bought my 2019 Envision a week ago Low miles certified Premium 11. Beautiful car nice ride plenty of pep with the turbo. Moonroof is awesome. Glad I got it AWD is good in the snow we got here in Vt

The dealership thorough, decent and interesting I found many autos that peak my interest. I also pass this info to my friends and family.

So far its been a good vehicle. It's drives and handles well. Safety features excellent. Gas mileage excellent. Hugs the road good. I like the camera in rearview mirror.

Glen great salesman very helpful highly recommend.5 stars good selection of vehicles .come down get yourself a whip

Bought this car after my wife said she missed her old Solara convertible. She loves it. Drives well. Extremely comfortable. Only complaint so far is that the trunk is small—and with the top down it’s almost non-existent. Her golf clubs ride in the front seat. We’ve only had it two weeks, so can’t comment meaningfully on reliability. But she loves it.

My recent service maintenance at Napoli Nissan was outstanding! Jeff, service adviser, was extremely helpful, courteous and professional. Jeff answered all my questions and concerns. I am a very happy Napoli Nissan customer. Thank You Very Much Jeff! John Maziarz

Dearrell was a great salesman. Everything was good fast past. I highly recommend you buy a car from here. They will work with you and find the of your dreams.

It was nice. No big problems and timing of service was good. Overall a nice experience.

I unexpectedly wound up leasing a 2022 Buick Encore GX. I have been very happy with all of the features and performance of the vehicle. It is peppy, handles great and is quite comfortable. A small step down in size from a Chevy Equinox and it has worked out extremely well.

We are happy with the staff and clean environment. Lucas and Rob was really helpful with the purchase.

I know that here in Northern California, Buick isn't a very popular brand, but that means I was able to get a stunningly good deal on my new '23. I traded up from a low mileage '18 Buick Encore (not GX), and at the time of the transaction, it had a remarkable trade value. My dealer did a outstanding job on pre-sale prep and delivery. My sales rep answered my every question. I enjoyed the prior vehicle, and feel this new one will give me the same kind of driving experience. My added safety feature is the front accident/pedestrian avoidance and lane keep assist. I haven't had to use either yet, but feel good about having them aboard. This Buick strikes me as a hidden gem, full featured but still available at a price point that blows the other comparable Asian built imports out of the water.

I?ve been going to Baron Nissan for years. I always get the best deals. I?ve shopped them around before, but I always end up coming back.

The reason why I am writing this is because I know the mileage is off because there is no way I can drive 100 miles in the city in one day it's not possible. This is a complaint for me because I feel it needs to be looked at.

Excellent communication. Was looking to purchase a used car online and Robert answered all my questions on a timely manner.

This car is a pleasure on longer trips. Comfortable driving seat and quiet ride. The turbo kicks in on the highway as needed with plenty of power and get over 30 mpg on the road. Our car has squeaking front brakes when backing up, but otherwise has had no issues. We haven't taken to dealer yet to get the issue corrected.

My family and I had a great experience at this dealership. Abraham helped us for our entire visit and provided us with outstanding care. I can’t recommend this dealership or Abraham enough.

The Regal is sporty yet economical and fun to drive! My son can't wait to turn 16 and be able to drive on his own!

I bought a car from this dealer (land Rover), everything went well , the staff were friendly and helpful. Special thanks to antoine wilson , he was very professional , helpful and kind. Thank you

Car is amazing. Handling is great. Very happy with the car.perfect vehicle,. luxury, gorgeous look, great on gas. Love this vehicle, very spacious. Big trunk..

I always receive prompt and courteous service every time I visit Arnold Chevrolet. I have serviced my car here since I purchased it from this dealer several years ago.

I bought this used with 26,000 miles in the spring of 2024. I love the styling, interior, and value. My only complaint is that the angle of the infotainment display can make it difficult to see due to reflections, especially in bright sunlight. I love the AWD option, it adds to stability - even in dry conditions. The remote start is handy in cold weather since I now live in an apartment and no longer have a garage. Performance with the optional engine is more than adequate.

Peter is a kind person and wonderful salesman. He is a credit to Ingersoll Auto Group! He helped make our lease go smoothly and efficiently. This is our second time we have worked with Peter to lease a new car, and he directs us to the perfect car for our needs.

This vehicle is so beautiful, the space is perfect. The modifications in the car are amazing. The vehicle drives very smoothly, perfect to take on a road trip.

We had a wonderful experience at NS Honda! We were nervous new buyers of an all electric Prologue, and the team at NS Honda was exceptional! Special shout out to Bill Binninger, Noel Ledesma, and Steve Cohen for their patience, professionalism, and amazing customer service! Great place to buy a car- they treat you like family! I would highly recommend NS Honda!

The car is beautiful inside. The seats are comfortable. I have a heated steering wheel and seated seats. The car has an automatic starter. I put high test in engine and the pick up is great. I put gas in the tank almost every two weeks. I love the car and would highly recommend it. Best car I ever drove.
