i was looking at '98 C5 front calipers that someone parting out locally. he was asking for $250 just for the front only. i think he's asking way too much. how much these go for? i was thinking of asking him if he will take $100 plus impact wrench and cordless impact gun. what you all think? forget the whole deal or try to barter with him? btw will the rotor from the C 5 works?
