The 2004 Audi S4 Quattro Cabriolet has a 340-hp V8 and a six-speed manual transmission. That takes care of the fast part. The practical is supplied by the four seats (hence the cabrio designation) and more-than-acceptable trunk space. The stickiness comes via Audi's famed Quattro all-wheel-drive system, which makes the S4 Cabriolet a true four-season convertible. The monetary value for this topless beastie is a lofty $56,000, but this is a bargain compared to the tags on the car's two direct competitors, the BMW M3 convertible and Mercedes' CLK55 AMG cabriolet, which sticker for $57,295 and $82,000 respectively. However, neither offer the adverse-conditions traction that the S4 Cab can provide.
