Steven was my Service provider and he was amazing!! He kept in contact with each step of the process. Couldn’t have asked for a better experience.

DealerRater Jul 1, 2025

Bryen Lovelady was an awesome salesman the entire way. Was willing to work a remote deal with me to start off, no xx, and followed through on his word until the very end. Super impressed with him and this dealership. Best car buying experience for me, by far.

DealerRater Jul 1, 2025

My experience buying a truck at TW GMC was hands down the best, simplest, experience I've had at any dealership. I was really impressed by how knowledgable the salesman, Bryen Lovelady, was about the specs, options and real-world capabilities of the trucks as well as the available inventory on the lot. I felt I got a great deal and was treated fairly from the moment I walked in. The sales manager, Matt Malin, checked in to make sure I was happy too. Top notch crew.

DealerRater Jun 24, 2025

Our point of contact, Gabe, worked hard to get us a quality vehicle for a quality price. We always felt well taken care of during the process. Great, honest work in a great facility.

DealerRater Jun 24, 2025

Wil and Michelle made the purchase of a vehicle painless! It was a super easy transaction.

DealerRater Jun 20, 2025

I was turned down and was told that they would not work on my truck because it had an interlock device installed. I will never give them my business again.

DealerRater Jun 20, 2025

My service advisor Steve was great to work with, he was quick to answer questions, get the service completed, and have me on my way. Would recommend Steve as a service advisor to anyone, it's why we've purchased three vehicles from Transwest.
