Here are my 2.
1972 280SE 4.5 W108 S-class and a 1978 450SEL W116 S-class. 300SD turbo W126 not shown because it's not considered a vintage under the terms of this forum. My W108 picture taken when I picked it up at David Morris Fine Cars, a Mercedes-Benz dealership in Edmonton, Canada, where I bought it for just $2,000 Canadian.
4.5 is not current and that image is before it's repaint.
