This place is great. I started with the ultra-inexpensive smog check, and was hooked.
My car is on the older side, so there's always upkeep necessary. They always check over everything, and give me a list of what they recommend, and are VERY honest about immediate needs vs. those that can wait.
I've never had my repairs exceed their quotes (which, as a woman, has happened to me in the past).
A warning: this place is ALWAYS busy, but they warn you if that the minute you walk in, or if you call ahead. They do not accept appointments. Just plan on spending a couple of hours, but there are fast food places within walking distance.
