I tested out an F10 M5 a few days ago and I was let down a bit. It's definitely faster than the E60, but it's also heavier, more isolated and more numb. It lacked the character of other M cars I've owned or driven. I could see myself owning one, but there was no feeling of "Wow, I need to have one of these!"

I also test drove one of those the same day (along with an E63 and an R8 4.2.) All I'll say is that I was also impressed by the 911 S. Really, really impressed.
