OK. Now I have to show my ignorance and ask "What's a 280?" I assume it's a Mercedes but what years? Is that an Otto cycle or a different sort of Diesel? And how the heck do Mercedes naming conventions work, anyhow? I think I've figured out that the number is engine displacement in cc's / 10 but the rest is sort of a mystery. I think a 300D and a 300SD have the same engine but the SD body is stretched - but I'm not sure about any of this. Maybe it all makes sense in German.

So the designation "280" has me scratching my noggin.
