If you happen to be in the area of Glasgow there seems to be a Z3 hardtop for sale with all the fittings that could essentially work out to be free if you don't mind taking away a rusty MOT failed 3.0 Z3 thats its attached to..then selling the car on..Its not mine by the way and usual precautions apply
