My friend didn't believe me when I told him about my 135i. He begged me for a ride at full tilt. His only words the whole ride "oh my.... what a torquey little bitch".
The standard disconcerting one (outside of a shopping center): "Is that an ///M-class?"
A 328i owner pulled up next to me at lights and gave a laugh while tapping his throttle, I had the last laugh.
