This 1975 Porsche 911 Carrera 2.7 Sunroof Coupe (chassis 9115400287) is one of only 395 examples built for the US market that year. Distinguished by a bespoke Paint-to-Sample Green (257) exterior over original Cinnamon leather, both specified from new and confirmed by factory certificate, the car retains its matching-numbers engine and gearbox. Refreshed roughly a decade ago and held by the same owner since 1985, it shows just 61,830 original miles and presents in highly preserved condition.

How this record is sourced

Each chassis record is compiled from public auction archives and links to its source material. Ownership, competition and maintenance entries are extracted from those catalogue listings by an LLM, which can make mistakes — please contact us with any corrections. The summary is Legacy Metrics’ own writing; we do not reproduce catalogue text.

“Full” and “partial” documentation labels indicate how well each entry is corroborated in the underlying sources, not an audit of the car’s physical paperwork. Names of recent or living owners are withheld for privacy.
