I will never buy a GMC from anywhere else. The dealership and people are real and not fake flashy like others. I drive further to get my vehicle serviced there over Jerry Seiner because of the quality, timeliness and communication from the staff.

Don't be fooled by just low prices - they all pay the same for vehicles. These guys know how to order new trucks with the right packages that won't cost you an extra arm and a leg. Save thousands by knowing how to order the right option packages on your next vehicle. Some dealers don't know how and you either get a truck with too many stupid options or not enough.

Best selection of trucks period! You can buy a new truck and build it like they do for a better price. Colby was extremely helpful and easy to deal with. He provided several options for my trade and financing. We needed up at the place that was fair and closed the deal! He even met me on his day off to pick up my new truck! Thank you!

We loved the Honesty and Straight Forward approach of Our Salesman, Hunter, he was able to address all our questions knowledgeably and we didn’t have to wait around for him to talk to anyone else. The paperwork was fast and easy. No pressure to buy a warranty, and he even filled up the gas tank. The best experience so far we’ve had with buying a truck.
