This is a great smog place they ones more helped me out. They gave me a discount for a coupon I took in and without hesitation took it from me. To get the discount they did not try to push any additional charges! That is great. Thanks Contra smog staff.

As posted on Yelp, here is my story: I took my Chevy G20 Van to get a smog check at Contra Costa Smog on April 6th, 2010. I was forced to take it to a test-only or Gold Shield station, so I could not use my usual, trusted shop. I brought my van in at approximately 11:30am, and was quoted a price of $79.00 and told it would be done in an hour. At approximately 12:30pm, I received a call saying there would be an extra labor charge of $50 for removing the engine cover of the van, making the total cost for this smog check an exorbitant $129. I regretfully accepted this charge, thinking it would be common practice at any shop for this additional cost (which I later found was not the case). I was then told it would be another hour until the van was ready. At 2pm, an hour an a half later, I came over to the shop and it was nowhere near being finished. I was ignored by the owner and was not given any further information about when it would be done. At at little after 3pm I returned to the shop and waited another 10 or 15 minutes to find out the results of the test - it failed. They claimed it failed on the emissions section, and that a smoke test would need to be done to find the gas leak. I was not about to give this shop any more of my money for the repairs, so I took my van to my usual shop. This shop performed the smoke test, found no leak and also tested the evap system with the evap tester - it passed the test, and cost me $85 to find out nothing was wrong. If there's nothing wrong, they can't repair it! The mechanic at this shop suggested that I take my van to another test only shop, get the certificate and return to Contra Costa Smog and demand my money back. Since my whole day on April 6th was wasted by that point, today, April 7th I took my van to another test only shop. It passed in about 45 minutes and at a total cost of $60 - needless to say there was no additional charge for removing the cover. I then returned to Contra Costa Smog to demand my money back, since by this point it had passed at 2 other shops. Also, in addition to the $126 I paid them, I had spent another $85 at my usual shop for them to tell me nothing was wrong, and $60 to actually get my smog certificate. The owner of Contra Costa Smog refused to give me any sort of refund, and said that I have to file a complaint with BAR. He then proceeded to tell me to, "get the f*** out" and called the police on me. Actually, he made a phony call to the police first which, of course, I did not believe. Then, when I continued to tell him to give me my money back, he looked up the real number to the police in the phone book and had an officer come down. I explained to the officer my situation and, of course, there was nothing he could or would do. He clearly was on the side of the shop, and gave me an attitude like I was crazy or erratic for even suggesting that the business had done any wrong. I am now hundreds of dollars in the hole and have spent hours of my time on this. I am a small business owner myself, and I cannot accept that any business (or human being) should get away with this kind of thievery. Contra Costa Smog needs to make some serious changes to their business practice, and I sincerely hope that this complaint helps illustrate their unprofessional and unacceptable service issues. Thank you for reading.

Couldn't ask for more from an indie mechanic. Brought my VW down for smog and the customer service I received was second to none. Brought the car back to CCS after having an engine light and some other general maintenance and experienced the same excellent customer service. For my VW they use Motul oil which is top of the line, very happy with that. When looking for a local mechanic I feel that honesty is key and Contra Costa Smog provides that 100% of the time.
