A 1996 McLaren F1 GTR prototype, chassis 10R, known as the “Pop Art” car for its distinctive one-off livery, heads to RM Sotheby’s Monterey auction on August 15 with a presale estimate exceeding $35 million. Its status as one of just nine examples built that year, combined with factory prototype specs delivering peak performance, already positions it as a blue-chip collectible. Long-term ownership by Pink Floyd drummer Nick Mason adds rock-culture cachet and documented history that appeals to high-net-worth bidders. Recent coverage has framed the lot as a potential record-setter, well above prior F1 sales, though actual hammer price will hinge on live bidding dynamics in a market where provenance, rarity, and timing can drive sharp swings.
