New and used 2026 GMC Terrain for sale near Cos Cob, CT

Sean my service provider was excellent and insured my interaction with the service department went smoothly.

I Love our new GMC Terrain… We had an awesome experience buying our car. The car was better than what I thought it would be!! Inside, It has great space.

John McCoy was a great salesman! He was honest, communicated well, and applied no pressure to make a decision. This dealership was the only one on Long Island that was willing to negotiate a deal on the car I purchased. Every other dealer said that they could not lower the price of the car even $1. This is the third vehicle that I purchased or leased from this dealership and I will return when I am ready for my next vehicle.

I have had many Jeeps, when they stopped making the Cherokee I was at a loss until I came upon the GMC Terrain and so happy I did. Great style, performance handles great, many exceptional features, I spend a lot of time driving and never feel like it is tiring, lots of room in cabin and the cargo area. I have a new favorite, and it is the Terrain

Great deal. No gimmicks or nonsense. Thanks Sean for making it such a smooth transaction. When it?s time to for another purchase I will certainly be back.

I’m 56 and I’ve mostly owned trucks in my life. Out of the few cars that I’ve owned this 26 terrain elevation edition is the best car that I’ve owned. It’s comfortable and expensive gets good gas mileage plenty of room inside well designedand GMC has been a reliable brand for me over the years. I do recommend this car.

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

This is a very beautifu vehicle, very dependable but the gas mileage could be better. With all of the new technology, it is somewhat difficult to remember all of the various control panel options. Also the owner’s manual is very skimpy.

Great experience and service!! Prior to pickup everything was explained and verified in order to have a seamless delivery experience. Sharon was great at going over everything and Mike took it home with no hiccups. Definitely great customer service and experience!! Would recommend and buy another vehicle!

Always great customer service. Excellent waiting area with fresh coffee and a good choice of goodies while you wait! I love the new computer system showing your car while you wait

Only thing I have to say is I wish I had purchased my Sierra truck from this dealership. I drove pass my purchase dealership just to do business with Rockville Center GMC Andy Melo and crew did a splendid job on getting me in and out and safely on my way.

Robert was terrific. Knew his stuff made it easy. Was expecting fees and nonsense but he made it happen

Rob Birchall and the team were great. Was towed in on a Saturday and they were able to diagnose the problem and have me back on the road in 90 minutes.

Buying my Buick was a great experience, they give you time to breath while looking around then approach for help and answer questions! Service area is alway great, always work with you to get the appointment you need! Will be leasing my next car from them for sure!!

Car was serviced for an oil and filter change and a tire rotation. I was in and out in one hour. Very please with the overall service and fast turnaround.

Amazing service team, tech kept vehicle clean and service Consultant kept me up to date on my needed services and repair, pricing is affordable and fair

Jim Kelly is an excellent salesman. We went to buy a pre-owned XT5 or XT6 and he was so patient with us and just made the whole experience a Real Pleasure.

Wilbur Pichardo was great! Efficient, Excellent communication skills and very professional. I Will definitely contact him again for his great service. Thank you
