take off your aftermarket wheels they wont add to the trade in price....sell them on ebay or local..youll get most of your money back...what kind of wheels are they??? try and sell your car privately..but keep in mind that you will save money by trading on the tax...
if they help him move the car it may be better to leave them on
rather than hassle with putting replacement wheels/tires on and then hassling again with selling the wheels separate too
