woudl you believe me if i told you didn't really know shit about cars til i got the repair manual to mine...then it all just clicked...? lol cuz it's true....not even a year ago i didn't even know what a crank shaft is....but now i can basicly be handed just about any car part from any car and tell you what it is...and what it's function is and so on...i guess tho i always had it in my blood...i was building skill lvl 3 (highest skill lvl of the smaller models) by the time i was 8-9
