Maybe if the M5 went on a diet it would have won! BMW used to make light weight M cars, what happened to that? 100kg more than the E63, wow
If not for the front of the E63 I would be all over it, I can't stand how the hood looks (emblem sticking up and grill) I like the looks of the C63 and CLS63 hood much better, not sure why they went old school with the E63.
BMW better watch their backs, CTS-V, E63, RS6 could all beat it and be cheaper (well two of the three, RS6 will be stupid expensive like always)
