Seller's Notes

This Porsche 911 2.7 is a characterful classic sports car, finished in a period-perfect colour scheme and with a rare specification. Powered by a 2.7-litre flat-six engine, paired with a four-speed semi-automatic Sportomatic transmission, driving the rear wheels. First registered in December 1976, this is an Australian-delivered example. The seller states that it is a matching-numbers example, finished in its original factory colours. The five-digit odometer shows 46,176 km, which the seller believes reflects genuine total mileage of 346,176 km due to odometer rollovers. Finished in Copper Brown Metallic paint over Beige interior trim. Equipment includes air conditioning, electric windows, and centre console. Accompanied by the original owner’s manual, significant historical records, and two keys. Please refer to the photo gallery to assess the exterior and interior condition. Specific notes from the seller include: There is a minor alignment gap at the engine decklid, which is an adjustment item and could be corrected during a future workshop visit. The front clip was professionally replaced in March 2026 due to rust. The dashboard clock operates intermittently and may occasionally stop working, likely requiring reconditioning in the future. The seller states that it was most recently serviced in August 2026 at an indicated 46,064 km, which included investigation and rectification of intermittent popping, all six spark plugs replaced, compression testing, ignition lead testing, and additional diagnostic checks. In July 2026, a new alternator was fitted by Autohaus Hamilton, and in March 2026 the same specialist completed a major service and other maintenance work. The seller reports that an engine rebuild was completed in September 2016 at an indicated 40,247 km by Harrisons RRR. Over the last 10 years since then, other work has included: an interior retrim by Healey Factory, the air-conditioning system replaced and overhauled, fuel and ignition system refurbishment by Pit Exchange; new fuel accumulator, injectors, and CDI unit; a replacement fuel tank installed, a new windscreen fitted, and multiple routine services. Sep 2016 - 40,247 km Oct 2018 - 41,029 km Dec 2020 - 42,691 km Apr 2021 - 43,398 km Nov 2021 - 43,638 km Jun 2022 - 44,010 km Jun 2023 - 44,587 km Nov–Dec 2023 - 44,928 km Mar 2026 - 45,288 km Aug 2026 - 46,064 km The Porsche 911 2.7 Sportomatic Coupe represents an intriguing chapter in the marque's history, with its innovative semi-automatic transmission. This Australian-delivered example, reported to be a matching-numbers car in original colours, benefits from substantial maintenance and refurbishment work over the last 10 years, including a documented engine rebuild and interior retrim. It would make a compelling addition to any collection of classic Porsches, promising a rewarding and exciting ownership experience for the next enthusiast.
