Doral's has been around in San Leandro longer than I can remember! And that's a long time! They have been taking care of our company van for a long time and just recently, I enlisted them to put a new engine in my personal 1998 GMC 3500 Sierra. It's running great and their warranty suggests that I'll have a minimum of 3 more years of useful truck life. I'm betting I get another 10! Great people, Great Investment!
