1955 Mercedes-Benz 300 SL Gullwing Coupé
- Engine
- 3.0L inline-six with mechanical fuel injection
- Colour
- Dunkelgrau (dark grey)

A 1955 Mercedes-Benz 300 SL Gullwing coupe, chassis 5500243, distinguished by its exceptionally rare Dunkelgrau (Dark Grey) factory finish paired with a red plaid cloth and fawn vinyl interior — recorded as the only example so configured in Eric Le Moine's authoritative Gullwing register. Completed in April 1955 to US specification, the car passed through a series of dedicated American enthusiasts before undergoing a comprehensive ground-up restoration by a team of California-based specialists using parts sourced directly from the Mercedes-Benz Classic Center.
