Corwin Motors Kalispell review
I went into Corwin looking for a specific vehicle.
I went into Corwin looking for a specific vehicle. Bailey Reed approached me and I told him I was interested in a truck on the lot. He went the extra mile for us to get what we wanted. He made it easy for us, I appreciate him a lot, he did a good job for my wife and I. This is the second time we’ve bought vehicles at Corwin, it’s our go to place for an honest deal.

KEY AUTO MALL - GM review
We've had a great experience with Key Auto Mall GMC
We've had a great experience with Key Auto Mall GMC purchasing our new 2025 Acadia. Brian MacGee was wonderful to work with along with General Manager Theron Maring and all the other great staff. Brian especially has spent a lot of time going over all we need to know about how this car works and has several times answered more questions since we purchased the car a week ago. He helped us purchase new cargo mats and get the protective coatings on the car, inside and out. Brian has been professional, friendly, and so helpful to us. We highly recommend Brian and the Key Auto Mall GMC team and will definitely consider them for our next auto purchase.

Went to just look at new cars, Wrong idea!
Went to just look at new cars, Wrong idea! We met Dexter and he was the best car salesman I’ve ever dealt with. He wasn’t pushy, He let us look, and then he gave us a few cars to look at at what he thought we would like. Found a car in a matter of an hour. Went back the next day and boom it was ours. They had the fastest and the best system at purchasing a car, simple and easy no more back-and-fort smooth and easy and I would recommend Them hands down.
