I suspect we have almost all watched Bangers & Cash occasionally, and from that gathered that there is a mix of old scrap, through to pristine examples of just about every type of vehicles available, and as it seems you may be in search of a classic, then perusing the stock of Mathewsons might give you a few ideas, might even be worth a visit via the web, and if anything of real interest turns up then perhaps a visit, though if you are up for a gamble I suspect if you bid over the phone for anything they might even deliver it...?
I doubt the distance selling regs might cover kit bought at auction, though I suspect if you offered to pay Mathewsons to use their expertise to supply you with a written pre purchase inspection, that might be an option worth exploring, or alternatively pay for an engineers report on anything that really takes your fancy..?
Whatever, best of luck and enjoy your research, which might be more fun than eventual ownership..? (-:
