While driving away from work tonight, I found myself "greeted" by a Civic Si (the '02-ish model) and a GTI at two different times, each one unable to resist revving their engines at me and pulling away after slowing down and blocking traffic in the adjacent lane.
I'd forgotten all about this aspect of M3 ownership. It takes me back to a day when JST came over to see me flailing away at the rear main seal of my busted S14, and he let me drive his E46 M3 on a brief errand. Back then, of course, it was a current-model car, and the number of stares, middle fingers, and other gestures of gratitude really surprised me.
Oh well. My first "mod" last night was to find the old ///M3 key fob that I used with my '88, and maybe my '99.
