I once sold a fully restored 1965 Mk.1 body-shell complete with boot bonnet & doors, all finished in primer. It was complete with V5, VIN plate(s), front sub-frame and suspension (separate from the shell as the shell was newly painted).
Two guys came a long way to buy it and paid what I was asking (it was not cheap!). The receipt listed all of this.
Then they admitted they had a Mk.1 1275 'S' 'basket case' and this shell was to be the replacement. All they had to do was to cut the hole in the tunnel and fit the boot board brackets and they had a Cooper 'S' Mk.1 shell.
I wasn't going to argue as they had paid me in cash
