My old 1989 Toyota truck failed a smog test at a 'smog test only' center and needed some repairs, which brought me to Antioch Napa Auto Care. I picked this shop from the positive Yelp reviews, and I'm glad I did. Eric, the owner, was honest and treated me very well. I left my truck at his shop and they discovered a rusted O2 sensor, which was the culprit. The problem was fixed and Eric was kind enough to re-smog my truck which passed. Two years ago my truck failed smog at 'Auto Tek Repair' in Antioch, which I will never go back to again. They claimed that the catalytic converter needed to be replaced, I didn't do the repairs, instead I went to another smog testing center and my truck barely passed. You get what you pay for, although Auto Tek Repair was less expensive then Eric's shop, it would have cost me twice as much to get the failed smog problem fixed at the cheaper shop. If you want professional honest work with attention to detail and quality, then Antioch Napa Auto Care is the place to go. Thanks Eric!
