How about an W140 S280, with a 5 speed manual transmission? I have only seen one, and it was a cab, waiting outside the Stuttgart airport. Had manual climate control.

A 350SEL (116 body) with a manual transmission...not too many of those around - also the last manny tranny V8 sedan the company ever made.

The 560SE had very low pruduction numbers if I remember correctly....

I think the rarity of most models is relative to where you live. I never see 116 cars - to much rust, A german has never seen a 300sdl, and most Americans have never seen an E220cdi. I dont think any of us have seen a CLK-GTR roll by, however.
