Used GMC Terrain SUVs for sale near Harwinton, CT

The expertise and professionalism and courtesy that is always shown to me. Joe Helayel, both as a Master Tech and Service Advisor is absolutely the best; I appreciate everything.

I always bought the GMC Acadia (4 times) but decided to try the terrain. I absolutely love it and it's a great car for zipping around in town. I would take it for a weekend trip but not on a long trip as it doesn't have a lot of cab room, but for two people it is fine

Great dealer. No hassle. In my new vehicle the same day. Smooth transaction. Very happy with whole experience.

I brought this truck in 2019. I kept taking it back to the dealership to get tweaked several times. Once it was figured out, never got any problems ever again. A little weak on the power side, but, other than that, its a magnificent vehicle. A total work horse. Great on gas. It is totally worth it.

Well I came 31/2 hours to see a car and it’s gone yesterday I wanted it I was buying it because i recked mine i wanted the same thing

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.

Had a great experience buying a car at Executive Honda. Rex was great to work with, put no pressure on during the process and got me in the best car for my family.

Great vehicle, 65,000 miles and not a single issue, hoping to get atleast another 100k miles out of it. Extremely reliable. A family member of mine bought a Honda that broke down at 16,000 miles and got stranded. Would absolutely recommend a 2018+ terrain

Joshua was very thorough with regard to the sale of the Maverick. Answered any and all questions regarding the sale? The transaction was actually done the same day. I was there with regard to ensuring and registering and selling the vehicle.

I leased this car before deciding to buy. Its a reliable vehicle and I have never had any break downs since I have had it.. just regular matenance

I bring my fleet vehicle here for repairs/maintenance. Other dealerships have treated me like a second class customer because the fleet company pays for everything. I have never once felt that way at Sullivan's. They are always kind and have gone above and beyond for me at times. My husband became a loyal customer here because of their great customer service.

Bought the car CPO in summer 2021 with 38k miles. Now being summer 2024 with 90k miles and I’ve mostly had good luck with the car and its components. I have the extended warranty through 100k miles but I feel like all American cars are built to fail after the warranty runs out. Overall great car: I have the 2.0L turbo engine with 9 speed auto and AWD. AWD is great when turned on, grips the road well, and to be honest the 2.0L has a TON of power; way more than you need for a compact SUV! I had a quick issue around 65k miles where the service traction control and stability light came on for 15 minutes. Dismissed itself and haven’t had an issue since. At 75k miles, it was during the winter time, the car would display “park break realized” and “service traction control” when the auto start stop would kick back on (there’s no way to shut off the auto start/stop system). No issues and lights but the messages would pop up and dismiss themselves. Little did I know it was my battery dying and my mechanic said “some wires were loose” and he tightened them up. Haven't had an issue since I got a new battery. Last thing that happens is sometimes when you have Apple CarPlay going and you unplug the phone, the infotainment system will freeze and no Bluetooth, usb, or CarPlay will work for the reming duration of the ride unless you stop the car and let it sit for at least 30 minutes. Simply shutting it off and turning it back on never worked. Overall I give this car a good rating for 0-100k miles. I am pleased with the car but looking for something bigger soon. I think I did overpay a bit for it ($30k for 38k miles) since I got it summer of 2021 when new cars were nonexistent!

Second time around was just as good as the first. It felt like visiting friends, not a transaction. I wouldn't hesitate to recommend Hamden for either a purchase or service. I'll drive further to get to this location since I know the time will be well spent.

I have owned my Terrain for 3 months now, and am absolutely in love with it. Super smooth, great pick up, and I get a lot of complements on both the exterior and interior design. I average 26.3 MPG city and highway combined, which is not bad considering I live in Florida so my AC is never off in the car.

Working with Ray to close the deal was amazing. He is very familiar with the vehicles and options available to the customers. He knows the material and how to get his customers to their end goal. Thank you Ray for helping us drive away with our new Truck!!!!!

25 000 miles on it so far No issues at all Power is fine Bluetooth is terrible Memory seats need work Lumbar is a bad design

Information on the vehicle was provided in a friendly and helpful manner.

2015 GMC Terrain Review – Reliable and Comfortable SUV: I purchased the 2015 GMC Terrain as a reliable daily drive, and it has exceeded my expectations in many ways. The interior is spacious and comfortable, with high-quality materials that give it a premium feel. The seats are well-padded, making long drives enjoyable. In terms of performance, the Terrain delivers a smooth and stable ride, with responsive acceleration that meets my needs. The fuel efficiency is reasonable, which helps with long commutes. The exterior design is bold and distinctive, giving it a strong road presence. Reliability has been solid, with minimal mechanical issues over the years. Maintenance has been straightforward, and the vehicle has held up well. Additionally, my purchase experience was fantastic, thanks to Claudia Reid/Sales. She truly took the time to negotiate pricing and ensure I got the best deal possible. Her dedication and professionalism made the entire process seamless. Overall, the 2015 GMC Terrain is a great choice for anyone looking for a comfortable, spacious, and dependable SUV. Would I recommend it? Yes, especially for families or commuters seeking a balanced vehicle. Thank you, Auto Club of Edison!

What a great dealership the people are fantastic super knowledgeable and helpful I’ve purchased 2 cars from them so far and go back for service all the time on my vehicles! Wow what a team definitely recommend this place to anyone who looking a car or looking to get their car service!!

READ PLEASE I love my Terrain. DO NOT get the 1.5 L. My engine has barely made it over 100,000 I have had $6k of repairs in less than a year. Things keep going wrong now. I had NO issues before. Catalytic converter went out 75-85k miles. My turbo was just replaced. Just beware of this type of engine… every mechanic that worked on it shared this is not uncommon for this type. I would definitely get another terrain but not the 1.5!

Our 2021 Terrain SLT is really a nice auto. Gets great 30 MPG approximately, But, 0 to 60 is lacking horsepower. Great Little highway auto. Comfortable.....

Thank you so much (Charlie) for helping my husband and I purchase the vehicle we always wanted. I saw how you went above and beyond to get us out of our current loan and always with a smile on and very positive. You kept following up with us several times throughout the day. People like to hear that. You gave us options and hustled for us. Honestly, even if the deal wouldn’t have gone through, I would have been happy because you really tried. I never thought the deal would have gone through because of our credit issues from two years ago and everything but you made it possible. I look forward to working with you again on our next vehicle. I will definitely continue to buy here and I will always recommend you as a sales person. I can continue to say nice things about Shamrock and hope they knows they have a great employee. The Wrangler is absolutely awesome and the modifications are subtle but awesome.

I really enjoy the Terrain. Traded in our beloved Mercedes R350. It was dream to driving on the highway. Our list for new vehicle was easy to get in and out without climbing up or down. No leather seats, hate leather seats, panoramic roof, engine power, get up and go, some luxurious in the vehicle, an easy info console. Before we took a test drive, we did our following tests. How easy to get in and out of the vehicles, leg space (our son is 6'4"). Only wanted two row seating, comfort seating. We checked all other makes. Spend awhile day going from different Dealerships of different makes and models. Didn't want to speak to car salesman, just let us do our preliminary test, on different makes and models. Then we look at the warranties. Finally took take a test drive. Was blown away at the get up and go of the Terrain, pleasantly surprised at the safety features and options it comes with. After almost a month, trips outside the city to the mountains and back. We are really happy with the purchase of the Terrain. Seven years warranty bumper to bumper, ten years on the powertrain. The true fuel economy really surprised me, it doesn't bother me that I have use 91 fuel because of the 2 liter engine. Had to use it on the Mercedes so no change there.

Extremely happy. Ride comfort, controls, comfort, looks, quietness, Quality. They should've kept the 2.0 turbo. But this engine not bad at all. Can't wait to get another.

So far the car is going great. We have had no problems driving everywhere and so far had no need for services. It is a great care for me and my husband,

In the past I have always bought a new vehicle and this was the first time ever that I have bought a used vehicle and I must say that I was skeptical at first not knowing what I was getting myself into. My experience with Juliani Motors was exceptional and my mind was put at ease. I was looking for a specific vehicle and the sales rep, Joe Hollaran, knew exactly how to steer me in the right direction and his knowledge was exceptional. Joe and the entire staff at Juliani were extremely knowledgeable and courteous. If anyone is seeking a used vehicle I would strongly recommend that you contact them as they have an expansive inventory of exceptional used vehicles. The 2012 Silverado I just purchased from them was exactl as advertised as to being in exceptional condition.

Great savings on gas and mileage, very reliable and comfortable. Saved my life when I was in a big rig truck accident as driver side and front side bags deployed. I've become a GMC customer for life as I will be looking forward to buying another GMC SUV.

Estamos muito felizes com nosso carro muito confortável muita seguro . Dar confiança ao motorista espaço bom para minha família eu minha esposa e dois filhos

The experience was amazing. My husband and I walked around for a few and here came Patrick the amazing car salesmen with a wonderful approach my question to him was are you ready to sell a car. He made the experience easy. He helped us pick the car that fit right for our needs. he was friendly honest and most importantly he saved us money . I’d recommend you guys go check him out.

Taking it on road trip Oklahoma to Key West Florida w/ stopover in Tennessee. I am getting 30 mpg running 75 mph. It handled like a dream going through Smokie mt. I was getting 32 mpg there. I like the ride on the interstates & I love the adaptive cruise control.

Had a great buying experience here at terryville chevy. My salesman Peter was great and very knowledgeable. I highly recommend going here!

We purchased the Denali Terrain 2023. The car is great. I have had four knee surgeries and needed a car to get in and out easily and comfort seating. The controls for adjusting the seat just the way you like are great. I am troubled also by back problems and totally love the heated seat when needed. Sometimes I just want to ride around and turn the heat on and adjust seat so my back feels better. The different controls and are numerous. I love the safety control warnings and info with traffic. The screen is fabulous and helps so much. When ever I park I like to drive in and park and then hold on brake put it in reverse so the screen then comes on and shows how I parked. I like the levers in cargo area for putting seats down and also like how flat they sit. Plenty of room. The back seat is roomy even when person in front is back. Enjoy being up higher than a vehicle. I feel I can see more and it also makes me feel safer. The Terrain looks beautiful and love all the chrome in front. The car seems bumpy but not as bad as our last. The roads are in rough shape here. It has a lot of pick-up my husband demonstrated that to me and he wont be doing that again unless it is necessary. It is a turbo 4 cylinder and can not believe the power you feel. All in all Iove the car and getting good mileage. Purchased car from Boucher in Waukesha. They were not pushy. Explained everything in detail and were very fair. Great place to purchase!

Personnel at this dealer were very responsive and followed up with me until I decided to buy a vehicle from another source (pricing related).

Perfect for a couple. Plenty of room and should be good for trips. Room for another couple when going out for fun. Ride is very nice and has a lot of safety features.

I had an outstanding experience purchasing my Cadillac Lyriq from Blasius Cadillac. Despite having researched the vehicle extensively through YouTube videos, sales representative Rich Noble took the time to thoroughly explain every detail during my test drive, ensuring I fully understood all the features. When I arrived late due to travel delays from Boston and a previous dealership appointment, the team was incredibly accommodating and flexible with my schedule. The pricing process was refreshingly transparent—we negotiated the complete out-the-door price entirely through email with no hidden fees or last-minute surprises. Most impressively, they coordinated with the Massachusetts RMV and delivered my vehicle directly to my home with plates and registration paperwork already completed, saving me an additional trip back to the dealership. Blasius Cadillac demonstrated professionalism, transparency, and genuine customer care throughout the entire process. Highly recommended!

This is my first suv and I was overwhelmed with the style and performance. I have been purchasing General Motor vehicles for a long time. GMC terrain sle is a outstanding investment. I'm enjoying my retirement and my new GMC 👶
