Mercedes SL Heart to heart

   View all

The yellow Mercedes-Benz SL roadster featured in the classic 1979–1984 television series Hart to Hart is an R107-generation model.

The Cars on the Show

• First Two Seasons: Jennifer Hart (played by Stephanie Powers) drove a yellow 1978/1979 Mercedes-Benz 450SL (R107) with the California vanity plate "2 HARTS".
• Later Seasons: The car was later updated/replaced in the series run with a newer model, such as a Mercedes-Benz 380SL.
• Other Hart Vehicles: Jonathan Hart drove a red Dino 246 GTS in the opening sequence, and they also owned a dark green Rolls-Royce Corniche convertible ("1 HARTS") and a Mercedes-Benz 300TD wagon ("3 HARTS").
If you're looking for information on these classic roadsters, let me know:
