1979 Lamborghini Countach LP400S Series I
- 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.
