The fantastic one-off Porsche 959 cabriolet is searching for a new home again

If you’ve got a million-odd quid sitting around, we’d like to draw your attention to the one-off Porsche 959 cabriolet adorning this very page, which has now reappeared for auction at RM Sotheby’s.

We first heard about it almost a decade ago when it was up for sale, and the story behind it is fascinating. Its first owner was said to be Jürgen Lassig, runner-up at Le Mans in '87 and winner of the Daytona 24 Hours in '95. He took delivery of his ‘Komfort’ spec - which gets a more relaxed suspension setup and full leather trim over the ‘Sport’ version - in 1988, before sadly getting involved in a big crash on the Autobahn that same year.

He then flogged off the remains to renowned Porsche racer and craftsman, Karl-Heinz Feustel, who spent 4,000 painstaking hours getting it back to road-worthy condition… and chopping the roof off to create a genuine one-of-one.

Other changes include a lick of ‘Grand Prix White’ paint and a reupholstered interior, now sporting blue leather with streaks of grey and cream along the seats. Feustel also provided a removable hard-top, plus an interchangeable ‘Speedster’ windscreen and spare door mirrors. You never know, you might get too close to a 25 route London Bus on Oxford Circus one day.

The 444bhp twin-turbo flat-six has been left in place too, you'll be glad to hear, and since this car weighs just 1,450kg, it’ll get to 62 in under four seconds and keep gathering momentum to 197mph flat-out. Mighty numbers, even by modern day supercar standards.

Reckon the price is worth it for one of the world’s rarest convertibles?
