It's $53 dollars with a credit card and only $48 with exact cash required! So I figured I'm in for the $48 but there was a problem with my suv because it needed an O2 sensor so I then took it to my mechanic and his name is Tim Lynch with T&K Automotive Repairs he does it in half a day and I go back to RJ at 101 Expressway Smog and the thing is you have to drive a certain number of miles to get the whole thing reset. RJ tells me this so I went out and drove it around for a couple of days take it back to RJ and he charges me next to nothing to have it done the 3rd. Time!! How great at that!!

Leaving it exposed to road debris. My car is older but I have taken it in anytime I had the slightest issues. But now $5k later it's in worse shape than ever and would be thousand of dollars to clean and repair all these issues.

Or both- sometimes, just taking reasonability for action is all a person needs to hear. But being meet with more dismissive behavior will only add fuel to the fire. Take responsibility, be accountable and treat customers like customers.
