Mercedes brochure from 1972, showing the 350SL (actually 4.5 liter), in its first year, in the US version: Rocker panels are body color.

Mercedes brochure from 1989, showing the 560SL (obviously US, as it was never sold elsewhere by MB): Rocker panels are body color. Unlike the earlier brochure, this does list two-tone paint as an option on the car.

Hope this helps--

Craig
