Precicely, if they are stupid enough to bid that much then let them, the seller must be laughting his head off and good for him too.
It's like Mercedes and BMW, I got no idea why they are bought for so much money as they are as common as heck, people seem to think they are being a unique majority. £25k for an A Class (a small car) is not unheard-of that's for sure.
I think some get too excited and are lead to belive that it's so special and rare, special maybe but rare it is not.
I'v also noticed that A1200 expansions fetch more then A4000 gear oddly.
