A few years back, BMW offered a funky coupe version of its M convertible, with both models being based on the popular Z3. It was a unique ride that offered a bit more functionality than its drop-topped sibling, as well as an added splash of individuality. Then came the M’s demise, coinciding with the launch of the all-new Z4, and that groovy hardtop was gone. Until now, that is, because the coupe is back. For 2007, there will be regular and extra-strength versions available, the latter being the Z4 M Coupe. Along with its unique styling, BMW’s newest hardtop delivers 343 horsepower, a five second 0-62 mph time, 18-inch alloy wheels, and an assortment of M-specific updates.
