After about five minutes of walking around a European auto show, you've come across half a dozen strikingly beautiful cars that have little to no hope of ever coming to the U.S. So all you can do is get in some intense ogling and move along. Pagani's Zonda Roadster F has gotten a large share of the voyeurs at Geneva's Palexpo.

All Zondas have a carbon-fiber chassis and bodywork, but on this car the exterior panels are unpainted, setting up a dramatic contrast with the yellow cockpit.
