Quite rare, but not many buyers, plenty of people want a few k for them, but they never seem to sell unless exceptional spec, so you could double you money really 1k to 1.5k as above

^ not sure why soo much for that one?
and the V12s dont command a premium, it seems the 728s do, due to its still a nice car , but the running costs are soo much lower.
Make sure its all good for 500, as said about leaky fuel tanks they are common, 1k new from bmw! and a fair amount of work to change, worn front brakes and thats 300ish for none oem stuff, front end wobble at 50mph, loads of expensive bushes!
My water pump failed, £600 in parts!
