Paid £500 for this last year. Bit tatty but had a years MOT, tax and runs nicely. 3.5 V8 EFi so is a bit thirsty, but will be much cheaper to buy than a Defender and if theyre looked after will go on for ever.
Mine also has working A/C, PAS, Elec windows etc. Huge fun to drive and comfortable, whilst being excellent on the rough stuff.
