A pleasurable experience working with Miguel Betz in purchasing my XT5. Miguel is personable, accommodating and just easy to work with. Knows his vehicles and doesn't try to push you in making your decision. He'll even throw in a little advice you can use if you choose to. I would recommend him to any friend.

We were driving up north when our 2014 Sierra decided to go haywire in the 400. We went here and Jonathon fit us in right away to take a look at it. The truck decided to work while it was in the shop so even though they could not diagnose the issue, they were awesome! Thanks for making a terrible situation a bit more bearable
