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

I have bought 5 cars from this dealership, and I have had nothing but great experiences. From sales, to service and the parts department. Cameron from sales is a great guy, and so is Skylar. The finance manager is wonderful, and works his butt off to get you approved with a payment that is manageable. I only take my vehicles to this dealership for service. Their service techs are polite, and always informative. I literally can’t say enough good things about this dealership.
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

Monica is great to work with, and a wonderful person to top it all off. Monica is easy to communicate with and very quick to reply to questions/emails. Monica always goes above and beyond to assist her customers. I have been working with Monica since 1998 and have purchased or leased probably 6 vehicles from her. I cannot give enough praise for all Monica does, and just the kind, caring, understanding person she is.
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.

Why I love Russ Milne
My first Ford I purchased from Russ Milne, 1967 Fairlane GTA. Loved that car. The salesman at that time was “Doc” Wilson. We have been dealing with Kellie Kraemer for many years now and we love her ♥️ We followed her from a different dealer. We would follow her anywhere. Her husband and son are always mosthelpful also. Thank You Kellie for being the best Barbara and Randy Frank

I had a big issue with my Buick enclave transmission, it
I had a big issue with my Buick enclave transmission, it is obviously a manufacturer issue, my car stayed for long while till the issue diagnosed and repaired, and I had to take it back again. I can?t deny that everyone in the dealership?s service department including service manager and my advisor did their best to make me happy, and actually I am! I got my car back finally and hope that the issue is solved forever and nothing else comes up, I am testing i for few days now. So thank you Serra Buick GMC Rochester.

Ron was courteous, efficient and helpful.
Ron was courteous, efficient and helpful. He spent a lot of time explaining the new features. He also provided me with the garage door opener which is no longer featured on the new Hondas at no cost. He always goes out of his way to help and be there when you need him. They don't make them any better than Ron.By the way this was a lease and not a purchase.
