I've been taking vehicles here for years, and have always been happy with the service. They are a smog-only business, which means they will not make any adjustments to your car, but the advantage is that they do not try to up-sell you with questionable service items like so many other shops. They have clearly posted prices that are based on the size of vehicle. They often have discount coupons in local papers, and if you phone for an appointment, and ask about the price, they will usually give you the coupon price, even if you don't have the actual coupon.
Pros: local, quick service
