Thoughts on the M5: I initially thought, wow, M division built an AMG! And I was right, and not in a bad way - this thing is a missile. I gave myself motion sickness in 3 launches (didn't use launch control). Steering is pretty damn good, but it's still a massive, heavy car. I haven't driven the all-new E63 but there are quite a few reviewers who prefer it over this car, so I can't imagine how much more fun the E would be. But yeah, the 500 tq is the major reason to buy this car. And almost no turbo lag, which I hated in all the N54/55 engines and the Mini motors I have to admit that the hated active sound really isn't obtrusive or feels like a factor at all Dislikes: rear seat leg room (come on, this thing is old 7-series long). Ventilated seats are completely pointless. It's not as pretty as a M6GC.
