Thanks for all the info! Looks like there's several veggie burners on this board. I bought a book call "From the Fryer to the Fueltank" by Joshua Tickell, that give a full description of how to make diesel from vegetable oil. There's a message board at www.veggievan.org that is dedicated to running diesels on recycled oil and I've gotten a lot of info from there. It's great to be able to close the information loop with all the Mercedes diesel knowledge here. I'm still looking for a car - there was a 300TD in the paper that I called on but got no response to my message. If anyone knows of nice 300's near Denver, let me know.
