Hailed by CAR magazine as the ‘nicest 911’ upon its 1982 launch, the Cabriolet would also prove to be the rarest SC variant with a mere 4,096 reportedly sold worldwide (the vast majority going to LHD markets). The marque’s first true soft-top in eighteen years, the model was lighter and sleeker than its successors thanks to a manual roof which sat lower in the hood well. Capable of nigh on 150mph, the 2+2-seater was just as much of a 1980s icon as the ‘brick’ mobile phone.

According to its accompanying history file, chassis 150375 was completed to UK market (C16) specification on 31^st December 1982. Supplied new to William Mochrie Esq of Edinburgh by Glen Henderson Motors Ltd on 7^th April 1983, the Porsche was in strong demand that decade being resold to Cambridge computer scientist Dr David Boris Johnson-Davies, renowned advertising agency Saatchi & Saatchi and H.H. & S. Ltd of Savile Row. Factory finished in Grand Prix White with Black leather upholstery, the Cabriolet was better equipped than its Coupe and Targa siblings. Maintenance records on file date back to the 1990s and show that the 911 SC was upgraded with stainless steel SSI heat exchangers and a stainless steel silencer at 129,356 miles. A new clutch was installed at 137,952 miles and the anti-roll bar bushes renewed some 3,000 miles later with the inlet manifold and ignition box being replaced too. Little used by its last registered keeper following a posting overseas, he nevertheless spent some £10,600 with marque specialist Precision Porsche during October 2023 having ‘TSG 627Y’ thoroughly gone through. New brake discs and pads were fitted all-round, the engine borescoped and compression checked and the fuel system refurbished etc. Having covered less than 1,000 miles since the work was completed (its odometer currently displays circa 141,000), the Porsche is understood to start and run well. Subject to refreshed paintwork and passing a MOT test with ‘no advisories’ on September 1^st 2025, this decidedly rare UK-supplied (C16) 911 SC Cabriolet is offered for sale with owner’s manual supplement, replacement service book, numerous old MOTs, assorted invoices and copy ownership records.
