I bought a car from them this week and was very satisfied
I bought a car from them this week and was very satisfied and impressed. I highly recommend salesman Christian Fernandez - he was very professional and made the process personal, comfortable and fun! He provided exceptional service. If possible call ahead for an appointment and come prepared, I'm from out of town Christian helped me get it all done in 1 trip, trade-in and all.

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

Excellent communication with my service advisor Robert. Timely work, and competitive pricing. I would recommend and do recommend this dealer to friends. i will use them myself in the future.
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

A friendly and professional customer service team - I was provided with all the information I needed and was clearly informed about the purchase options. There was no pressure to buy or hard sell.
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.

Paolo was our salesman and he was beyond helpful, kind,
Paolo was our salesman and he was beyond helpful, kind, and easy to work with. I had been talking to Rachel through emails and she set everything up for us, as far as what payment we wanted. She got us just we asked for. We then went to the dealership and Paolo helped us with the rest of the way. He showed us the truck, ran numbers for us and made it work so that we got the payment we asked for. This was my sons first experience buying a new car and it could not have been a better experience. The manager there also came out to talk to my son and be sure he understood everything about the lease. I thought that was awesome. There was at no time any feeling of being rushed, or being pressured to buy the truck. We went home to talk about the payment and 2 days later bought the truck. I WOULD RECOMMEND ADVANTAGE AND PAOLO TO ANYONE LOOKING TO BUY A CHEVY TRUCK.
