Calling all Steve McQueen fans: RM Auctions will sell the King of Cool’s very own 1967 Ferrari 275 GTB/4 at its flagship Monterey event in California on August 15 to 16.

Painted a distinctive shade of metallic gold called nocciola, the vehicle on offer, chassis 10621, was special ordered by Hollywood Sport Cars for the actor in 1967 while he was filming The Thomas Crown Affair.

McQueen, known for customizing his cars, sent the car to be repainted chianti red prior to taking possession.

He also requested that 10621 be fitted with the Borrani wire wheels from his beloved 275 GTB N.A.R.T. Spider, which was a victim of an unfortunate earlier crash, as well as equipped with a custom-designed driver’s side rearview mirror, a retractable radio antenna and custom seat trim.

Once complete, McQueen took delivery of the car while on the set of his legendary 1968 crime-drama Bullitt.

It remained the only Ferrari in his renowned stable of sports cars for almost five years.

In 2013, the car was displayed at the Museo Ferrari as part of the From Cinecittà to Hollywood: Ferraris in the Cinema exhibition (above).

The final hammer price could easily go north of $10 million, setting a record for the model.

But not every prancing horse was ridden by the King…
