It is a tough time to sell a used Hummer. But used Bugattis, Mercedes Gullwings and other rare auto breeds for the well-heeled still are fetching top dollar.

A few minutes ago, Gooding & Co. released the final tally for its annual Pebble Beach auction. The California sale, which follows the storied Concourse d’Elegance, is one of the elite car auctions in the world and has become a valuable barometer for the collectible-car market.

This year’s auction, which ended Sunday, raked in $64.2 million, topping last year’s huge tally of $60 million. Twenty cars sold for more than $1 million–more than triple the number in 2006. Five cars sold for more than $2 million. The Bugatti collection sold by Peter Williamson, comprised of 12 prized cars, sold for more than $15.5 million.

Granted, it wasn’t all good news. One in five cars failed to sell.

Still, the number of price records shattered this weekend suggests that the rare-cars business remains strong.

Here are of some of the blockbusters:

1937 Bugatti Type 37SC Atalante Coupe–$7.92 million, the highest price paid for a vehicle in North America.

1959 Ferrari 250 GT LWB “California”¯ Spider–$3.63 million

1938 Alfa Romeo 6C 2300B Mille Miglia “Sleeping Beauty”–$2.585 million

1950 Ferrari 166 MM Berlinetta Le Mans–$2.2 million.

Three cars from Oprah Winfrey’s collection, including a 1954 Mercedes-Benz 300 SL Gullwing, sold for $716,000.

What does the auction say about the economy or the wealthy? The prices imply that there still are a limited number of prized cars sought after by a larger number of rich people. It also suggests that, as with art auctions, car auctions probably are benefiting from the relative well-being of the super rich as well as the overseas rich, who are taking advantage of the weaker dollar.

That doesn’t mean the collectibles boom will continue forever. But for now, it’s still rollin’.
