During an extended stint behind the wheel of the new BMW M3 Coupe in Monterey, California, motorguru.com jumped at the opportunity to take to the track in the more 'mature' M3 - the four-door sedan version. Where better than a racetrack to experience the true capabilities of the M3. The weight distribution and performance of the sedan is nearly identical to the coupe, so the word 'compromise' was far from our minds. With the introduction of the sedan, BMW has opened up the M3 to a whole additional set of buyers who can now be responsible and naughty at the same time. Wow, what a car. Now you can take your friends along comfortably for the (thrill) ride in an M3.
