Fantastic place - got me out of a jam for much less than I expected. Over the weekend, I hop in the car, drive 3 blocks, and my car's engine starts going nuts. The tachymeter (i think that's the dial that tells you the RPM), drops to like 500, and won't go above 1,000, even though my foot is on the gas. Damn.Unfortunately I live at the top of a big hill in Pacific Heights. To drive to the top, you generally have to downshift to 3rd (or lower) and rev above 3,000 RPM. So I was screwed. I tried going uphill, but the engine sputtered out. I had to swallow my pride, put it in neutral, and roll BACKWARD into a parking spot.I looked up Advanced on Yelp and was sold by the great reviews.So how do you get a car to Potrero if you can't rev above 1,000 RPM? Answer - very carefully. I got it moving, and coasted down the hill, and drove across town at like 15mph, running stop signs the whole way. I left it with Advanced, and braced myself for the worst. But they hooked it up to the computer, found the problem fast, and fixed it quickly and inexpensively. The whole experience was too good to be true. I can't remember the last time I heard a mechanic say "Take the care back now - I don't want to do extra work if I'm not exactly sure if there's a problem." The honesty and competence is a refreshing change of pace...
