The first U.S. spec Audi R8 V10 sold at auction for $150,000 more than a Ferrari California.

The first Audi R8 5.2 FSI V10 was sold for $500,000 in a Florida charity auction. The auction was held at the 2009 Boca Raton Concours d' Elegance to raise money for the Boys & Girls Clubs of Broward County.

Amazingly, the Audi R8 V10 sold for about $350,000 more than its estimated sticker price. It also sold for $150,000 more than the 2010 Ferrari California. That Ferrari will probably have similar U.S. pricing as the Audi.

The person who bought the 525 hp Audi R8 V10 offered the auctioneers the opportunity to re-sell the car a second time to raise even more money if Audi agreed to give him the second U.S. spec R8 V10. Audi agreed, and the second auction raised another $350,000 for a car with a sub-four second 0-100 km/h time.

Aside from the amazing engine, the all-wheel-drive Audi R8 V10 has a lightweight aluminum frame. It has been considered by many to be the most eagerly anticipated car of the last year.

When all was said and done, the auction raised well over $1 million for the Boys & Girls Clubs.
