Drove a 2009 Porsche 911 with A/M before I drove the M3 6spd. The 911 didn't impress me. The M3 blew me away. Got it will all the options and brushed aluminum. It is very comfortable. Takes a little time to get used to shifting the manual. You can tell a major difference from M mode and regular mode. Fuel economy is almost the same in both so I usually just leave it in M. In M it is a rocket, in regular my 4-runner accelerates faster. Icontrol is easy to use and they seem to have thought of everything and put it in the right place.
Stare factor. Several people have nearly wrecked their cars trying to stare at mine. M-Mode, engine note in M mode. IControl, cool remote controlled convertible top, voice commands, handsfree phone, sat/HD radio, nav, heated seats in cool weather top down driving, thumb drive MP3 ports.
Vent leather seats w/AC. They don't get too hot but no air can circulate there (steamy). More HP, fstr 0-60 for convrtble & better MPG (turbo charge it). Better placement 4front license plate. I don't want to drill holes in the front bumper. Free rock chip insurance & buffing w/free maintenance (?)
