2008 Porsche Cayenne GTS Preview – 2008 Chicago Auto Show: For those who can't afford the Turbo with their S, Porsche has an answer: the 2008 Cayenne GTS, with more power, a manual transmission and a more sporting suspension. It's built for drivers who have to drive an SUV, on a budget, but like to put some fun and challenge into their daily grind. Other upgrades include Porsche’s active electronic damping and air suspension as standard equipment, redesigned sports seats front and back, extended wheel arches and new body work front and rear. The GTS goes on sale in the U.S. this month with an MSRP of $69,300.
