Drove the M5 at COTA last summer at M Track Days. It is definitely badass. Easily hit 144 down the straightaway. However, I love my M550. So much better than the others I have owned (including the M4). My only problem, at age 71, is getting out of it....not so much in to it. If I trade, which I am not currently contemplating, I will probably go with an X5 with the V8 (not necessarily an M), which are hard to find, I understand. Just because I can climb in and then fall (tumble) out!. All you young guys.......just wait. You'll find out what I mean.
