The first rays of sunshine in the sky: Passionate convertible drivers can barely wait for the beautiful moment. Of course, this is even more beautiful when there are three to choose from. Mercedes SLK, Audi R8 Spyder, and BMW 645i. Three vehicles of different character. The Mercedes is the sporting roadster. The green paintwork and the two stripes underline its ambitions. The Audi R8 is the uncompromising racer. This is emphasised by the red paintwork and the two stripes. The 10-cylinder engine accelerates the two-seater made in Neckarsulm to 313 km/h. The BMW 645i is completely different: Despite its generous V8 engine and 333 HP, it in fact glides smoothly - but all the same up to 250 km/h. On the eye-catching model, painted light blue, the black folding top can be removed.
