This is also now on eBay from a private seller. Very special too as it has a V6 
"1971 BMW 2800 CS Classic Collector Low Miles V6 3.5L RWD Manual Stick 5 Speed"
It does have an M90 and dogleg. But I am not sure about the "mint" classification. Terms of mint and perfect get thrown around too much and looking at the standards of the seats and can see the scratches to the belt line trim I could not go as far as mint. That said, it does look to be in reasonable shape.
It is also from the same state as mine was...
