get an older E32 735 straight 6,them buggers are indestructible
we had 2 of those in our family , both went 5 times around the clock, and then the clock failed...
299 999 km's... times 5 you do the math
btw, they kept running after that
one still does, one got totalled by a tractor with a big load of manure (what a way to go)
those engines had not been opened
worst failure i can remember was a busted radiator...
very comfortable car for long cruises, the seats are probably more comfyr then those in your living room ...
btw, and you can drift those barges , has to be wet
and it's VERY scary
