00 A4 1.8 T from NJ in need of help!
 

My Audi is parked for the past month. Too small for a car seat so had to get a suv. Would like to supe-it-up but don't know much. Would a car club help or what is best?

Best bet is to read the new owner sticky posts in the B5 A4 subforum here. That'll give you a lot of basic modding info. Also, there are other members here from NJ who may be willing to meet up with you and help you out - check the NE regional forum on here and see who's around you.
