An incredible collection of Ferraris spanning 50-plus years of the company's history goes up for auction this Sunday at the Ferrari factory in Maranello. The stars of the sale are undoubtedly a 1961 250 GT SWB California Spyder that belonged to The Magnificent Seven star James Coburn, which is estimated at $4.6 - $5.9 million; and a 1964 250 Le Mans, est. $6.5 million - $7.4 million, making it one of the most expensive Ferraris ever to go on the block. There are plenty of other incredible machines on offer in the Ferrari: Leggenda e Passione event being staged by RM Auctions, however.

Our personal favorite is this beautiful 1962 250 GT Lusso, the very first production unit and one of only three known examples raced, which is considerably cheaper at est. $1.2 million - $1.5 million. Other highlights include a 1990 Ferrari F40 Le Mans, est. $1.5 million - $2.1 million; a 2004 Enzo specially made for a member of a Middle Eastern royal family in a one-off shade of gray, est. $1.2 million - $1.5 million; and a dashing dark blue 1967 GTB/4, est. $1.2 million - $1.6 million. If you can't make it to Italy this weekend, LiveAuctioneers.com has opened bidding online, and will also carry streaming audio/video of the event.
