Right off 325 BMW

[snapper]

Just followed a 325 BMW on the back of a tow truck to a yard after it had been stuck in a ditch on a straight bit of road by Chav-U-like, the reg was covered but it looked like a tidy 2 door probably around the P reg.
It wont be released until the insuranve has been dealt with but its a definate insurance right off.
Have i just found the ideal donor for my roadster project?
Do i use the whole powertrain and front hubs or is it a mix off sierra as well?
