Had an out-of-State vehicle that wasn’t up to standards. The folks at the Smog Shop advised me on what the car needed in order to be tested. The vehicle failed a couple of times because of some old parts, but they kindly advised me of some of the little things that would cause failure, and mentioned places to go where I could save money on those parts. The car was then close, and the guys at the Smog Shop ended up doing a little fine tuning, and it finally passed. They didn’t charge me for all of that extra time! Although smog testing is a necessary evil in CA, the Smog Shop kept me fully informed, and in a kind manner.
