The guy at the 16th street store refused to give us a smog certificate, even though the vehicle passed, because he claimed not to be able to find the number on the catylictic converter. The converter was stolen in 2008 so we went to the Midas down the steet where the replacement had been purchased. (They are excellent) They put the vehicle on the lift, gave us the number and we took it back to the smog guy. He then claimed we couldn't prove purchase of the converter. We went back to Midas, got the receipt and took it back to the smog man. He wanted an additional $30 to retest!!! We called the pertinent state agencies and filed a complaint. Don't trust this business.
