This 1941 Chrysler Thunderbolt, a very early example of what would now be called a concept car, was another interesting offering from RM in Scottsdale for 2006. Claimed to be in the best condition of the four remaining examples, it fetched more than $1.2 million (including buyer's premium).
Golden era car
RM Auctions usually offers some European sports-racing cars of the "golden era," which was best represented this year by this 1955 Maserati 300S. Its enviable competition record across Europe in the 1955 and 1956 seasons helped it bring $1.9 million (including buyer's premium).
