I am disappointed with my experience at this establishment and I wanted to share my experience so that others would know what to expect. I went to this business ONLY because they sent me a coupon in the mail for a smog check. My van was coming up for registration and I needed a smog check so I stopped in while running errands. My husband was the driver, he left the van running and the door open so the smog test could be performed. I was in the passenger seat getting my things together so I could get out of the van. I placed the large coupon on the center console right next to the driver seat where the man got into my van to run the smog test. The test lasted less than a minute (which was great) but when the man told us we passed and the asked for payment I handed him the coupon and he told me I needed to present it to him BEFORE the test. The smog technician refused to accept our coupon. This bad review is more about principle not the extra money it cost for the test. What extra service did this man provide us that was any different that with the coupon? What difference did it make if I gave him the coupon before or after the test? Poor business decision in my opinion, I will never go back nor will I refer friends.
