Bubble pricing with that £275k Audi, once the current generation of 40-50 somethings that era means something to are dead it'll be next to worthless, I'd say.
Same thing is happening with classic fruit machines, £2k for some 'classics' now, ten years ago I sold a mint 1985 machine for £1, cos that's what the market thought it was worth.
Nowadays same machine working, even in poor nick, £500
