:dontknow: ... what can I say... I gotta defend my daily driver
... I've driven them both... neither is better they're just different... keep in mind if you test drove a new M5... it's restricted to 400HP the first 1200 miles... your first tune up @ 1200 gives you the 507 option... I've seen 4.1-4.7 0-60 numbers on the car e60... just depends which magazine you like..
The mercedes looks better and rides nicer... I'll give it that... you should definitely check outt he 08e60 m5... if you haven't already.... btw... test drive a used one and be sure to hit the M button
... smg ftw
that's my 2 cents... just trying to help.... don't mean to hijack... good luck :>.... that's an 06qcnr beside it
