Quick calculation - the parts as listed (minus the seats, doorcards and boot install) add up to about £1200(adjusted for bartering and such)
I would take £750 for the car as it stands. That would mean someone could attempt to do it up and if that fails, they can still sell the bits and not lose out.
Anyone interested in that? (I'm struggling for the time and space to break it myself, and the only bits people are interested in are the bits that would completely disable the car!)
