I get snide comments about my 335i from colleagues and worry about customers seeing it.
I sell software to the public sector, so need to be a little careful - hence mine is stock looking. I think an M3 would be a step too far in my company, an SLS would cause utter mayhem!
Car: 2010 Jaguar XFR (Cat-back exhaust)
Gone but not forgotten: Highly Modified E90 335i LCI M Sport Manual (circa 480BHP/500lb ft)
