Does anyone here have a e39 M5 as well as a e53 X5. I've always wanted this particular pair of vehicles in my driveway.

As some of you know that 2 weeks back I was a victim in a head on collision totalling my X5 at freeway speeds. I'm looking for a replacement vehicle and i'm leaning to something such as an M5 as an alternative measure, until I find a suitable e53 4.6 or 4.8 of course. =)

I'll put this questions out to the X5 family first! What does X5world think/know of the M5?
