The BMW M6 Convertible may suffer from a lack of identity – is it a sports car, a luxury convertible, or both? But nobody can deny that the German automaker has done the car some favors by blending an aggressive design with serious performance capabilities, bulk and mass notwithstanding. That two-hit combination has propelled the M6 Convertible into a legitimate choice in its segment, and the public has responded in kind, giving the car enough appeal to stand on its own amidst a cacophony of challengers waiting to knock it down a peg or two. The M6 Convertible’s appeal isn’t just limited to customers; it’s also become an attractive project for aftermarket tuners, a lot of whom have taken to building tuning programs for the two-door drop-top. One such tuner, G-Power, is even bringing one to the year’s biggest auto show in Geneva.
