I will tell everyone I know that I know jack shit about cars. Though I can hold conversations with my mechanic, and understand most stuff... I have found myself hanging around my mechanics shop a lot (he lets me use his tools, watch him, shoot the shit, ect ect) and I am learning a little from that. I have found though, that a lot of my lack of knowledge comes more so from not having the right tools to do the job. But yes, it really upsets me when I see people who do work on cars yet don't know what they are doing, and say they do. Many of times I have asked friends for help on my car who say they know what they are doing and in the long run I end up fixing / installing the part and they are sitting down doing nothing, without a clue in the world of what they are doing...
though this thread was probably created for people like me (buying a supra with no clue what the fuck the engine holds, nor what can or can not be done to it) but... I have one distinct difference, may not know everything, but I sure as hell will NOT buy cheap parts formy cars, no matter what kind they are :-D
