With just over a month to go before the Concours d'Elegance begins, there's more rumors about the priceless (and pricey) cars that will be on exhibition there. The Los Angeles Times reports that Porsche will debut its new Panamera, a four-seat sedan, at the Concours d'Elegance. AutoWeek, meanwhile, has a photo of the Jaguar XJ, set for its US debut in Pebble Beach on August 12. While it's set to have its world debut this Thursday, Americans will have their first chance to get an up close and personal look at the Concours d'Elegance. New Zealand Classic Car, meanwhile, has a gorgeous gallery of the Ferraris that will be featured at the Concours d'Elegance.
