Some guy was driving quick. Knew he wanted to race. I was ahead by only about 1/2 a car, raced from a stoplight also, i didn't start above 3000 rpm and still won. I was surprised how quick he was, it wasn't an M5.

No mods.

 

Probably a 545 (if current modely), which is pretty powerful. Or could even be previous generation 540i Sport. I hate BMWs- good thing you didn't let him win.
