Yes, the R170. In 1997, they were only available with automatic, so anything after 97 I'd be able to find a 6-speed box easily.

treetops: The W210s have proven their longevity so far. I wouldn't see why I couldn't get another two hundred out of this car easily, depending on how it runs in the winter. Even then I can just use a block heater if it is a little weak. They have no problem with longevity it seems (which I never doubted), and handle miles really well. My source of Biodiesel would be a friend making it for me, I haven't found anybody else in Philly that does it.
