January kicked off collector-car auction season with a big bang and big dollars. Following Mecum’s $275M haul in Kissimmee, Florida mid-month, the traditional Arizona auctions added about $245M more to the tally, with $200M of that from Barrett-Jackson’s no-reserve sale in Scottsdale. Bonhams, though, had the highest-priced auction sale in Arizona, with $5.175M buying a Bugatti Chiron Super Sport 300+ (as in 300+ mph test-track capability) for a car with just Bugatti’s test and delivery miles.
