Superpart
Superparts I just got some from the boss wht can I used them for I have no cars for them ????
looking at your rep level i'd hazard a guess that you've not been playing the game long and aren't very far into the underground, on that basis i'd sell those parts to get the scrap points and use those points to buy parts at the chop shop for a car that you can use them on so you'll get quite a big boost and save time on having to grind for parts
I dont think its worth keeping them as its going to be a very long time before you'll have a car you can use them on, personally, if you're far enough into the underground to have unlocked the mustang i'd grind bps to get the mustang up to 4 stars and then buy epic muscle parts for the mustang
although i'm sure other players may suggest doing something different
