salvage auctions - not my fav. as thet often sell for more than worth.

Car auctions, woma - oxford, any local, bca is good, go to an auction full of trade and few punters, the trade don't like 4-pot petrol alfas so they always go dead cheap, diesels too.
You also get non-runners at auction, take a gamble, must be cheap, don't come up often mind.
