Great first time buying experience with the folks at Lehmer’s. The staff there treated my wife and I with kindness and respect from the moment we stepped foot on the dealership. The made the buying experience painless, not to mention gave us a great deal. We left feeling happy and optimistic about the dealer we chose to purchase our new GMC Canyon from. I also had a great first few dealings with their parts department! They were great help with my new accessories that I recently purchased as well.

I had great support from Chico Dixon to locate the vehicle at another GMC dealership. He worked with dealership leadership to work out a trade for the truck that I was looking for. It took a few days and they were able to work out the details. Chico kept me up to date each day as to the progress until it was fully completed. In addition, he worked to also get me a good deal on my trade. Chico was so kind, friendly and up front about everything. I would recommend Chico and Lehmer's to anyone looking for a new GMC.
