I went to Richards Auto Clinic to have them take a look at a car I was considering buying. They charged $100 to make a list of some of the problems, but were unable to identify where or how many leaks oil leaks the car had, or why the check engine light was on. For an extra 60 dollars on top of the first $100, they'd do a "diagnostic" and look for why the light was on. I thought I was already hiring them to see how the car was running? Anyhow, they said they didn't know how long the car would work. The car owner and myself parted ways, and he drove off down the road. I was with my friend, who drove in that direction as well. She saw the car broken down on the side of the road two blocks away, and her diagnostic was free!
