I'm a BMW dealer, and from the day it came out, I have said the M850 is the best and most well-rounded vehicle BMW sells. It makes me happy someone agrees with me
It's funny the N63 sounds so good in the M850 but the S63 sounds like crap. All the MPA models honestly are better for day to day use than the true M models, and I've driven them all.
Enjoy many more happy miles!!!
