The most expensive single-car collection ever sold during one auction fetched more than $67 million, showing continued strength in the collectible car market.

Twenty-five cars, all owned by an anonymous Florida collector, were sold Thursday night by RM Sotheby's in a standing-room-only sale as part of the Concours d'Elegance auctions and shows in Pebble Beach, California. The sale total beat the previous record for a collection from a single owner of $65 million.
