I had my 2020 Terrain for 5 years before I had any major issues out of it. My brake booster needed replaced. After about a month of it being out the shop someone hit and totaled it. Very sad day. I love my Terrain

Great Reliability
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

Short Story: These guys are the real deal and exemplify
Short Story: These guys are the real deal and exemplify what used car dealerships should be. Long Story: Myself (fellow salesman 7+ years) and my father (mechanic 30 years) are probably the most difficult customers to deal with when it comes to buying cars. Kevin and Dan "put up with us" :) and aided us throughout the entire buying process, as I was buying out of state and had been burned by used car dealers before. Yes, every dealer has some sort of "fees" (certification/documentation), but BOTH were lower than the local BMW dealership as I have both quotes in front of me as I am writing this. (In reference to the few negative reviews): If you cannot figure out that "$2,000 down" or "$2,000 trade-in" will show you a different sales price than the bottom line of the vehicle, y'all need to do more homework. If you have any questions JUST ASK, they are beyond honest and I look forward to purchasing from them again. Their honesty made me feel secure and confident in my purchase. - C
I LOVE the power
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.

Great experience
My husband and I stoped by to look at a VW Jetta for our daughter. At the time, the car was not at this location. Lou made sure the car was there the next morning and we were able to take a look. Over the next few days, Lou was extremely patient with our hectic schedule as we completed the process of buying the car. My husband and I both agree, this was the best used car experience we have ever had, with outstanding customer service from Lou and his team. We would definitely go back the next time we are looking to purchase a car. Thanks Lou!
Exactly what I wanted.
I absolutely love my vehicle. It is reliable and comfortable. I recommend this vehicle to anyone that wants an SUV and is looking for a change.

Kevin sold me my first non-Jeep car! I am so satisfied with his skills in helping me find what was suitable for me and my lifestyle. He was patient, non-pushy and I had the best car shopping experience yet.

Quick turn around
Went in for service, hoped it was under warranty, it was! Car was done well before I could get back to pick it up. No more issues! I owned 4 Dodges that I got from Videon, this was my first Chevy. Same great service, different location.
