One Stop Muffler & Auto Repair, Lancaster CA

I have a smog test issue. Nothing wrong with the vehicle, it's a simple sensor malfunction. Mercedes are notorious for this. The mechanic knew but didn't offer to correct it, he tipped his hat and pointed with his nose and said "there's a secondary air injection pump right there" and he walked away after charging me for the smog pretest. I did the research and inspected the pump. Looks fine, I'll have to remove it to further test it. The pump, if broken, is inexpensive and simple to replace, but One Stop didn't suggest or offer to render the issue. I went to a mechanic for service, you would expect better. I give it a double thumbs down. I'm a non mechanical civilian driver who has the money and was reaching out for help. I have to do this myself and pay again for another smog test. Nice job there One Stop

Pretty reasonable place in price to get your smog checks done you're in and out no long
