I bought my M3 in December with 71k miles...had been looking for one for three years before this one rolled on the lot. It has been everything I hoped, and I've even managed to get 21 mpg combined city/hwy. The ride is a little bumpy, largely because of the tight suspension and low-profile tires. But every time I drive it, I get a smile on my face. I don't drive it hard, but I do look forward to on ramps, and it's nice having "video game" speed whenever I want to pass on the highway. Press the accelerator, and it takes off. The stereo is good, but not great, and the factory navigation is obviously a bit outdated, but still neat to have.
Great acceleration, strong braking, Heated seats, On-board computer, rain-sensing wipers
Upgraded factory stereo package could be better, Key is kind of clunky
