Late this fall, Porsche had a media gathering in Elkhart Lake WI for the Panamera (just after the SCCA Runoffs). They had twenty of them under a big tent with a half dozen Cayennes thrown in. I do admit, it looks quite different in person and actually better than I expected.
A friend has one on order, so it will be interesting to gather first hand. SPEED had a pretty good show last week with test drives and commentary from Laguna Seca.
