Re: accident... who is at fault ? :(
Mate, found myself in a similar situation a few years ago working as a taxi driver.
Backing out of a motel complex, badly lit, pissin down with rain, cars parked along the drive making it more narrow than usual and drove the step from the passenger side of the van straight across a brand new set of mags. After checking, there was minimal damage, but because they wouldn't let my boss see the damage for himself, it was tossed out.
Unfortunatley man you may be in some what of a pickle, the best course of action from my point of view is to work out some sort of arrangement with the van owner, but get it in writing as well, a gentlemans handshake only goes as far as the victim allows it.
Best advice ever given" DON'T PLAY WITH IT...OR IT'LL FALL OFF"
