Drew was there from our first call until we went home
Drew was there from our first call until we went home with a new Chevy. He worked hard to get us where we needed to be financially. Explained everything we needed to know about the vehicle we purchased. Drew was also there for some follow up calls, very patient and kind. We will definitely return for our next vehicle

Ben Sheppard was great to work with. Knowledgeable and experienced. Only reason they didn’t get 5 stars is the time it took to get our paperwork done

Johnny in the service department went above and beyond
Johnny in the service department went above and beyond getting our vehicle repaired. The vehicle wasn't purchased from Transwest but had an extended warranty with it. All of the issues were repaired and part of it couldn't be covered by the warranty. I felt like Johnny worked with us every way he could to make things right !! Thank You

It was definitely worth the stop!
I stopped in with my son, a first time buyer who was looking for something to tackle the snow with. As soon as we stepped out of our vehicle, Dominic approached us with a friendly aura and introduced himself with a smile. Ya know, most of the time when you’re greeted that fast as a auto shopper you’re thinkin’ uh-oh another pushy salesman, but that was far from the case. This dealership was helpful and willing to give us a car buying experience that was unmatched by previous lots around the region. The staff is friendly and treat you as one of their own. I will send all of my friends and family here first the next time they’re lookin’ to buy a car.

Harrison Barnette was very understanding of my unique
Harrison Barnette was very understanding of my unique situation. My home and a vehicle had been destroyed by the November 3rd tornado in OKC. I found a very similar truck online, and Harrison was somehow able to hold the truck even though I had no firm date for delivery due to everything that I was experiencing. I couldn't have asked for more, and Harrison went above and beyond. Everything was set up when I was finally able to get to the dealership. It was my smoothest vehicle purchase ever. Thanks again!

Since I was seeking a rare used car, I bought this car
Since I was seeking a rare used car, I bought this car online with only a FaceTime view ( I had test driven one prior but missed out on buying it). Agent Jaydon was very helpful throughout the process, reassuring this anxious buyer, assisting in financing and arranging to ship the car. Still awaiting the closing details, but so far am very pleased ( and I told the sales manager so).
