Driving through Grand Junction, on a long road trip, our car developed a brake problem. Brian Burford, the owner of the shop, met us personally, diagnosed the problem immediately, ordered the part and had it delivered to the shop, and installed it right away. He had us back on the road in the shortest possible time, and charged a very reasonable fee. I can't recommend this shop highly enough. Thanks Brian for your outstanding customer service!
