Where I knew one of the mechanics. He, however, was not an emissions tech. They tried to tell me that my car needed possibly thousands in repairs, that it was dangerous to drive it (which, since I had just come off a thousand mile trip without a problem, I doubted). By the time I was done, the station was on a military blacklist, and under new ownership. I many not know much about cars, but I know when Repair people are trying to rip me off.
