Another heavy hitter from RM Sotheby’s, this McLaren F-1 is estimated to fetch between $21 million and $23 million once the bidding has closed. That might sound high for a regular F-1, despite these supercars being highly regarded, and it is. What’s different about this is it’s 1 of only 2 F-1s modified by the factory to LM specifications. Among the upgrades is an Extra-High Downforce Kit and an unrestricted GTR racing engine. This McLaren has been well-maintained and preserved and has under 14,000 miles on the odometer.
