Classic Vintage Mercedes-benz

- "D" means the vehicle is equipped with a diesel motor.
- "E" (for "Einspritzen") means the vehicle's engine is equipped with petrol fuel injection. In most cases (the 600 limousine being the exception), if neither "E" or "D" is present, the vehicle has a petrol motor with a carburettor.
- "G" denotes the Gelandewagen off-road vehicle.
- "K" was used in the 1930s, indicating a supercharger ("Kompressor") equipped engine. One exception is the SSK, where K indicates "Kurz" (short-wheelbase).
