Well done!
Regular service, oil change, grease and tire rotation. The car needed a good wash and they did that too. All very timely and at reasonable cost. We bought this car used and have been getting it serviced here since buying it. Service has always been wonderful.

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

The absolute best experience I’ve ever had buying a
The absolute best experience I’ve ever had buying a vehicle. No pressure sales or games. Fair prices and trade in values. Taylor listened to what I wanted and was personable, quick, efficient, and just a great guy. Same with the finance guy (sorry I forgot his name). The vehicle I was interested in was already washed , had gas and waiting for us. I will never go anywhere else.
MY TERRAIN

Customer response
I love this dealership and the service they provide. The people are very friendly and courteous. I would definitely recommend this dealer to a family member or friend
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.

Completely Satisfied
It was a pleasure dealing with Elvin and Tanner at Keystone Motors. We live in Western NY and searched far and wide for a van that met our criteria, which included originating in a Southern state, or a state with roads not exposed to winter salting. Elvin was friendly and conversational when I called about the van after seeing the listing online and provided me with great information. When we arrived at the dealership after driving 4.5 hrs we found the van in the condition described. In fact, it seemed even better. They sent us out on a test drive alone so we could really focus on getting to know the van and checking it out. We went on to check out another van that afternoon and Tanner held the van for us without a deposit until we confirmed with him that evening that we would purchase it the next day. The purchase process was easy and streamlined and Tanner even waited with us at the notary for our transport tags. The showroom and restrooms were very clean and very family friendly and had toys and books for our children to play with while we made the purchase. They had a good time there. Neither Elvin or Tanner were pushy, and we sensed a lot of integrity in both of them. There were no processing fees and they stuck to the price they gave me over the phone before we drove down which they had lowered from the original listing price. They did not present any unwanted add on warranties or guarantees, just a great vehicle in great condition. The work they had done to it was very professional. I drove it the 4.5 hours home and didn't have a single worry.

The first day I showed up no one assisted me or asked me
The first day I showed up no one assisted me or asked me any questions so I left. I then reached out asking if the vehicle was still available and was responded to very quickly. When I showed up to look Jeremy helped me right away and was very kind. Let me see all the seats because I am looking for a third row. Unfortunately that car was not right for me and he didn’t make me feel bad or like I wasted his time he was just happy to help me. I really appreciated that.
