Don't feel bad! Theres always more room to learn! for someone to know everything there is about cars is quite absurd. As someone mentioned before (and what I'm involved with) try to get into a school with formula SAE. I can tell you a lot of general info on fieros or challengers where as someone else on the team knows everything there is about subarus and someone else about mitsubishi. (I still can't get all those wierd engine and turbo designations down IE : R34) but I love to learn!
