The 2008 BMW M3 Convertible delivers an exceptional driving experience, especially with the double-clutch transmission, and cabin tech is first rate, but options quickly jack up the base price.
When BMW announced the newest M3 Coupe last year, it quickly followed with this retractable hardtop version. Where the Coupe has a carbon fiber roof, the retractable hardtop mechanism adds significant weight--441 pounds.
Although sports car aficionados might object to the convertible top, it does let you hear the engine better. But the top does add weight, and when down stows in the trunk, shifting the car's balance toward the rear.
The Power button is standard for the M3, and sharpens throttle response, while the EDC buttons, for the electronic damping control, are an option. The button behind the shifter changes the transmission program.
