Delage's pre-war straight-eight flagship — the D8-120 being the celebrated coachbuilt model.
Delage's straight-eight flagship; by the D8-120 era (1937–39) built under the Delahaye partnership on Delahaye mechanicals but with Delage's own straight-eight, an outstanding basis for the era's finest coachwork.
Right-hand drive.
The last truly great Delage — a blue-chip pre-war straight-eight whose value rests almost entirely on the quality and provenance of its coachwork.
