[320i]

hey guys,i just turned 15, and i just sold a quad, to buy a 1992 JDM imported Bmw 320i. The only problem is that i don't know much about this car, but my dad knows quite a bit about these beemers. So do you guys have any CD"s made that guide me through some cool steps on how to replace stuff, or how to even change some things on it. BTW what motor oil does it take? it says absolutly nothing on what oil to use and i cant find anything, and its really hard without a manual. And where is the battery located??
