This Porsche 911 SC is a highly engaging and extensively restored classic sports car, presented as a desirable RS backdate. It is powered by a naturally aspirated 3.2-litre air-cooled flat-six, driving the rear wheels via a five-speed manual transmission. First registered in 1978, this 911 was previously registered in the UK and is now located in Australia. The odometer indicates 6,374 km, though this is not warranted, and the seller states that the odometer was zeroed when the full restoration was undertaken. This example is believed to be a 1978 911 SC Martini Championship Edition, which has been comprehensively restored and backdated to 1973 RS specification. Build year: 1978 This example is finished in Grand Prix White with contrasting blue bumper stripes and 'Porsche' side decals, over a black leather-trimmed interior featuring blue and red tartan cloth inserts on the seats and door cards. It rides on a set of 16-inch Fuchs alloy wheels finished in blue with anodised lips, fitted with Falken Ziex tyres. Equipment now includes an Alcantara-trimmed Momo steering wheel, a wooden gear knob, electric windows, heater and ventilation controls, RamAir foam air filters, and a Becker Mexico electronic cassette stereo. Externally, this 911 SC has been backdated with F-model RS-style bumpers, F-model front indicator and horn grille units, the removal of the side sill trims, and a 'ducktail' spoiler. Accompanied by its owner's manuals, the service booklet, car history documentation, photographs documenting its service history, a collection of maintenance invoices, UK MOT certificates, and historical documents, a letter of origin from Porsche, and two keys.
