I'll be jumping ship as soon as I can to either an M2 (#1 on my dealers list) or an F80. I own a highly modified 2er so while yes my car will absolutely crush an M2 in a straight line, I know I'll be able to tune the M2 to a high power level also. However IMO the M2 will be a way better looking car from an aesthetic standpoint straight out the box. As simple as it sounds, thats my deciding factor. Looks.
Shameless plug
