As you'd expect with a car priced in the M3's range, all trims feature luxury elements, including 18-inch or larger alloy wheels, xenon headlamps, power windows/locks/mirrors, cruise control, automatic climate control, heated power-adjustable seats, and leather upholstery.
All M3s also feature an AM/FM/CD/MP3 stereo system with auxiliary input. For the convertible, the multi-panel folding hard top opens and closes in about 25 seconds, and definitely counts as a cool bit of mechanized wizardry.
Optional upgrades include the Technology Package that adds the M Drive system and other driver-controllable handling and performance elements. A la carte options include Bluetooth, navigation with real-time traffic, satellite and HD radio, 19-inch alloy wheels, heated front seats, a sunroof (at no cost on the sedan), and iPod connectivity.
