Good numbers are hard to come by for overall sales figures from the six classic car auction houses that just finished holding sales in Scottsdale, Arizona. One thing is certain, the classic car market is roaring. By some estimates, this year’s sales in Scottsdale are 40% ahead of 2014, and that may be a very conservative estimate.

Barrett-Jackson alone had $125.9m on 1470 cars sold; Gooding made $51.5m on 114 cars sole (90% sell-through); Bonhams did $24.3m; and RM Auctions dominated the top 12 list with half of the leading sales, all Ferraris.

Thus far in 2015, Ferraris dominate the list of the top-ten highest prices paid for a classic car at public auction. After the Scottsdale, Arizona auction week in mid-January, eight of the ten most-expensive cars in the world in 2015 have been Ferraris. Two concept vehicles by General Motors are probably the more surprising classics on the list – if these are excluded, all top-ten cars are Ferraris.
