My m535i's are valued roughly between £750 and £2000 (top whack).
Mechanically identical to 535's which are worth less if that helps.
There are no better features on a m535i over a 535i bar the kit. 535i's have the same suspension, lsd, interior the lot as a m535i.
Shouldn't really tell you all this as it de-values my m535i somewhat but hey, fuck it.
M5's came with or without the kit at the owners discretion, although i have seen lots more on-line without I have only seen a couple real ones in real life and they have all had the m-tech kit on.
Real ones have better suspension, arbs, engines, diffs, interiors, brakes etc etc but there were only 187 rhd ones sold here afaik which makes them pricey and a bit thin on the ground. A lhd Spanish import tipped up at BMW sunday last week which was rough as assholes and that still cost 3.5k.
cant be 100% sure its genuine yet but its badged up, full tech1 kit, and a twin exit centre mounted exhaust. I cant put pic up really cos i think i was trespassing but its sat in a yard full of old cars waiting to rust away, although it looks pretty tidy to be honest! smashed rear light and some mold but otherwise ok on the outside. i have reason to believe the guy who owns the place has died, in time i want to get in contact with someone to see about buying it... but how much do you think its worth? obviously it has no tax or test and its been there about 2 years iirc. thanks 
. so what sort of money do these make, i assume they are getting quite thin on the ground these days? 
200k miles!! Then he said, errr no - 300k
