heres the skinny on mirkos: if you drive daily with them on IT WILL GET THRASHED OVER TIME!!!!!! its an unavoidable consequence. you will be repairing, repainting, or touching it up often. no way around it, unless its only on for the occasional show.
i wouldnt have bought a used mirko for that much anyway. i got mine with a huge chunk missing and repaired, primed, painted, cleared, etc. by myself and spent under $200 when it was all said and done.
regardless of who did what, whos fault it is, etc. ALWAYS ASK FOR PICS!! who just sends money off without seeing or asking many specific questions about the used product anyway?
bottom line: i hope this works out for the best, for both of you
