Ultimate Drive at Gearhart BMW in Denville NJ today. One thing I noticed with the "fun" button, I pressed it when I was driving steadily on highway (Rt 80) with my right foot on gas pedal unchanged in position, the M3 got a sudden boost with that press action (kind like a turbo cut-in).
BTW, the e46 M3 and other bimmers are white this year, not silver (I was too excited yesterday).
