Audi R8 V10 sells for $500,000 at charity auction

Which would you pay more for--a V10-powered Audi R8 or the new Ferrari California?

At the third annual Boca Raton Concours d'Elegance in Florida last weekend, the Audi R8--the first one in the United States equipped with the 5.2-liter V10--was the winner in a charity auction, selling for $500,000, well above the car's sticker price of $180,000.

Meanwhile, the Ferrari California was snapped up for $350,000, a bit more than the $225,000 sticker price.

Overall, the event raised more than $1 million for the Boys and Girls Clubs.

Race driver and team owner Bobby Rahal was given the Automotive Lifetime Achievement award during the weekend event.
