The overall numbers weren't the biggest surprise of the weekend. A 1936 Mercedes 540K Special Roadster (see my “test drive” here) topped the price list as expected, but it didn’t break the $15 million mark that collectors anticipated. Meanwhile, a 1960 Ferrari nearly staged an upset, coming in a close second place at $11.2 million.
Here are the top 10 sellers for the auctions run by Gooding, RM, Mecum, Bonhams, Russo and Steele.
