The Car Connection's Take

TCC’s Bottom Line
The 2010 Audi S5 / Cabriolet might be the most handsome German luxury two-doors available-and are surely among the best performers. The 2008 Porsche Boxster performs brilliantly, and looks and feels the part, delivering a modern take on the classic roadster experience.
