The upcoming RM Sotheby’s Monterey auction on August 15 drives sentiment for this 1996 McLaren F1 GTR chassis 10R, nicknamed the “Pop Art F1” for its distinctive one-off livery. As one of just nine 1996-spec GTRs built—and the first of only two short-tail prototypes—this road-legal example carries strong provenance from its long ownership by Pink Floyd drummer Nick Mason, amplifying collector demand in a market hungry for blue-chip 1990s icons. The presale estimate in excess of $35 million positions it as a potential record-breaker, well above prior F1 sales, with momentum fueled by its rarity, documented history, and timing amid Monterey Car Week’s peak visibility. Traders are watching for any last-minute provenance updates or comparable private sales that could shift final hammer expectations.
