A glorious Porsche 911 Turbo that belonged to the former owner of TAG Heuer will be offered up at Bonhams’ Spa Classic Sale in Belgium on May 18.

Estimated at up to $550,000, the 1983 time capsule was commissioned by Mansour Ojjeh, one seriously rich dude.

He ordered it with 935-type bodywork and an engine tuned to produce 375 hp, an increase of some 25% over the factory standard, amongst other options.

Ojjeh no longer owns the Porsche, but he still owns a large chunk of McLaren, so he’s probably not walking to work…
