I have a 1974 115 240D, and this is the oldest M-B I have ever owned, and there's much I don't know about these years. Right now, I'm trying to determine of the wheels on the car are the proper ones. They are just plain steel 14 inch wheels. Was that the original equipment, where the hubcap rims and caps were put over them, or did they have the magnesium wheels in 1974?
