I read all the positive reviews on line and decided to give them a try. My cars starting having problems while driving to Las Vegas from San Diego. I took it to DI Auto explained to them I was only in town for two days and if they could expedite this. They gave me a ride to and from my hotel and had completed all the work by noon-ish. Turns out a coil in the eng had failed and it needed a tune up (I was meaning to get a turn up for months, 80k+ miles and never had a major one done). Out the door for less than $300. I'm thinking there are other shops out there who would take advantage of out of town emergency cases. Not these guys.
