This star-spangled banner themed Lamborghini Diablo is one of the very few Diablo SV-Rs (Sport Veloce - Race) that were converted for road use. It also was the only American entry into the Lamborghini Supertrophy Series marking Lamborghini's first official racing effort. You can see it in motion in the clip after the jump. Or even better, you can drop by eGarage for the full story about this amazing machine and the complete high res photo gallery.
