Doing my usual search for a nice E34, I came across this BMW : bmw hartge H5S
I don't think it's worth £6k, but it could be very nice with a bit of effort. Needs better seats, for a start.
Also on ebay, so depending on what the reserve is, someone might get it for a decent price. 1988 BMW HARTGE H5S | eBay
If it was black or grey, I wouldn't have posted it and I'd be on my way to see it now
