The car is absolutely fantastic. I knew it was going to be fast but I wasn't prepared for it to be this fast. I had a remapped 535d before it and I thought that was quick, that was nothing compared to the M5. I love it, I'm only a week into ownership but so far so good. Tried MDM traction today and I must say it makes the m5 feel like a different machine again. You can actually put your foot down without the ecu acting like your Mrs.
