1979 Lamborghini Countach LP400S Series I

1121078roadItaly
Engine
3.9L V12 with downdraught 40 IDL Weber carburettors

A 1979 Lamborghini Countach LP400S, one of only 50 Series I examples built, distinguished by its optional V-shaped rear wing and a unique engine modification: a previous owner, Heinz Steber, had a Luxembourg specialist refit the V-12 with downdraught 40 IDL Weber carburettors matching his Miura, a configuration the car retains. Spending most of its life in Germany and Switzerland, the car received a thorough mechanical overhaul and respray before entering its current ownership, and presents in well-preserved condition with its original navy blue interior intact.

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.
