MB Diesel Search

[E300D]

So after we got the 95 E300D, my uncle cought the diesel bug as well. Currently he's driving a 98 S320 and he would like to get a diesel, especially when one looks at the gas prices! Anyways I told him about the E320 CDI, however it wont be until few years when those cars become afffordable. I also told him about the W124 2.5 TDs, 3.0L NA ones, W210 diesels, W140 350 SDLs... Is there any other diesels that I have missed?

In our area, southern Ontario, there really isnt too many good MB diesels for sale. There is a W140 SDL with 388K, with new engine for 24 grand.

Also, would anyone know a website that shows all the MB models that could be bought with diesel in Europe?

Euro MB taxi cabs are mostly diesel, what are the most successfull engines used, W123, W124 etc?
