Bought this one owner, 60k mile, FBMWSH, 540i Touring as a winter smoker last year... was quick, still made 155mph but it had extra smoooooth power delivery and being an SE it was extra comfy and boaty... the seats were the optional versions which adjusted in pretty much every way and were unbelievably comfortable. Fitted some genuine staggered 18" Alpina alloys which transformed the way it looked compared to the standard 16" SE alloys.
Would I have another E39?? Yes... but only an E39 M5, decent non-M versions are almost impossible to find anymore, I got lucky with my 540i.
Cheers,
Grant
