And the more you learn, the less people will take advantage of you. I know it is more common with women customers, but some mechanics take advantage of everyone that doesn't know where the dip stick or air filter is. My father-in-law blindly took his GP in for some work at a "reputable" mechanic. The guy took advantage ($800 USD) for a chain reaction of repairs that started with a $30 oil change. (An oil change for $30.00 is bad enough, but every time that car went in, it came out with something else that "needed" replacing).
We reported the mechanic to the BBB (Better Business Bureau), but they are still in business. My father-in-law won't trust me to fix his car until it is too expensive to have done at a mechanic. He is getting better at trusting me.
