Other bodystyles : This coupe will be the first M3 to break cover: a launch is expected later this year, with RHD sales starting spring 2007. Next year will also bring the launch of four-door saloon versions and, later on, a cabriolet and even a Touring estate. Most exciting, however, is the prospect of a limited-edition stripped-out, lightweight CSL model, giving a good 440bhp.
