Though it has already graced the covers of countless magazines and has been written about ad nauseam, the 2006 Porsche Cayman made its official debut at the 2005 Frankfurt Auto Show. Priced at $58,900, the Cayman offers up 295 horsepower from a 3.4-liter, six-cylinder engine that pushes this German sports coupe to 60 mph in 5.1 seconds with a six-speed manual transmission, or 5.8 seconds with an optional five-speed Tiptronic automatic.
