Have:
Nada
Want/plan to:
iDrive Retrofit for non-iDrive car
OEM HID/Xenon upgrade
Hamann HM Style CF Lip
M-Tech Rear bumper
19" VMR Wheels in Matte Black
KW V2 Coilovers
Let's be real, if I wanted a super fast car, I would have gone with a 335i.
That's why everything you see, aside from maybe coilovers, is all aesthetic.
