I used to chide the NAPA parts guys "You spose Micke Waltrip uses this crap on his race car?"
Frankly I buy a lot of stuff at O'Reallys. Same Chineseo crap but at least I get a military discount there, for what little that is. Some of the parts "men" know just as little at either place, and frankly, O'Reallys has a couple of females that are both fairly sharp. The young one, at least, is not arrogant.
