Both Denver and his wife Vicki are wonderful people. Denver does exceptional work and will get to the root of the problem before he releases the vehicle to you even if you really need it. He's not going to let you drive out unless he's 100% sure that it works. Knowing that it was very expensive job he actually worked with me to bring the cost down. I have nothing negative to say except that they're exceptionally busy and they deserve to be so. I recommend them highly for intricate work in addition to the everyday oil change.
