Agreed @JBOO, you have a E60 535d, the fastest/greatest diesel on earth today, (un)fortunately not available with a 6 speed manual
272BHP an 600Nm.
OT:I 've driven a few E60s and must say this: Comfy and sharp, but the smaller(and less weight) the more agile.
I prefer a 5/7 E/S with a bigger engine + autobox.
Smaller cars need manual or SMG like trannies.
