One of only 100 of its kind, this Irish Green Porsche 904 GTS is expected to sell for well over $1m, and it comes with A-list credentials.

Actor and Sundance founder Robert Redford has owned the car for close to a decade. The car manufacturer designed the model in 1964, having shuttered its Formula 1 programme and focused instead on sports car racing. It produced just 100 road-usable models, using the same fibreglass technology that had made the Lotus Elite so revolutionary.

The 904 debuted at Sebring International Raceway, where it won its class and went on to take high places at successive racing events. By 1965, Porsche abandoned the 904 in favour of the more popular Carrera 6.

Bonhams is auctioning the lot and notes: ‘The 904’s star may have burned only briefly, but it was both bright and glorious.’

This model is believed to be only the second 904 delivered to a customer. Its original ‘Silbermetall’ paint was replaced first with dark blue and a silver nose, and then Irish Green – however, Bonhams believes it could be restored to its silver livery. The car is expected to fetch somewhere around $1.7m dollars at auction.
