Some might take it as a sign of depressed times that the car fetching the top price at the "no-reserve" Barrett-Jackson Palm Beach Collector Car Auction this month was a 1969 Chevrolet Camaro. But maybe the $500,000 that changed hands signals that times aren't as bad.

Even with nameplates like Rolls-Royce, Bentley and Aston Martin available, American cars dominated the big-bucks side of the three-day event in Florida. Of the dozen cars receiving the highest bids, six were Chevys, including two Corvettes. Three were Fords ( F), joined by a California-assembled Ford-powered Shelby. An Oldsmobile 442 and an Indiana-built, V-12-powered 1934 Auburn 1250 Salon, once owned by actor James Cagney, rounded out the U.S. domination of the 12 highest-priced cars to cross the auction block.

This 1969 Chevrolet Camaro RS/SS received a top bid of $500,000 at the Barrett-Jackson Classic Car Auction in Palm Beach, Florida.

Although the location name is associated with the mega-rich, the Palm Beach auction attracted buyers and sellers representing a cross section of car lovers from blue collar to white shoes, including big names like auto-world icons Carroll Shelby and Rick Hendrick. This delighted Barrett-Jackson Chairman Craig Jackson, who told TheStreet.com that his job is to sell quality cars that are saleable, and this requires a diversity of vehicles and bidders.

The auction was fully consigned, with more 100 vehicles turned away. A total of 487 vehicles changed owners for a total consideration of slightly more than $20 million. Although high-rollers bid 29 cars to more than $100,000 each, including 10% buyer premiums, a total of 202 went for less than $25,000 apiece. Half the vehicles fetched less than the median price of $30,800.
