I have to say, the V10 M5 is quick no doubt, but it does not feel fast really? I suppose with 500Bhp & 2000Kgs it's only 250bhp/tonne?

Beautiful motor, but very hard to see where it sits for the average car enthusiast now, too expensive to run daily, too heavy & not really that "special" to keep as a weekend toy, plus mega maintainence costs outside of BMW warranty! I can see good E39 cars being worth more than the E60s in the long run?
