Title kind of explains it.. I was thinking the other day and alot of people can't afford brand new parts for every single thing on their rides.. So what are the good pieces to buy used (obviously price is the biggest factor) but what parts are good buys that are ok to buy used and not worry too much if your getting a good part or a pos. I would say safe bet buys are shifters and CAI's. What else out there are good used pieces to pick up?
