What car models are best for biodiesel? Anyone done the full conversion to vegetable oil? [more inside]

I would like to purchase a high-mileage / low-emissions vehicle which I can drive (alone) in the carpool lanes around the Bay Area. Hybrids present one option, though I'd rather be in a diesel VW Golf, running biodiesel. I need help figuring out the requirements listed here to see if a diesel Golf meets them. And does anyone know if filling it with biodiesel changes anything? What other vehicle options are there?

I love my car, but am becoming increasingly concerned about gas mileage and environmental responsibility. It isn't a guzzler, but I know I could do better. What are your experiences with diesel cars? [more inside]

Fuel Filter? Has anybody had long-term experience using North American bio-diesel in a TDI? My dealership is dead-set against it, but my European friends swear by it. (I tend to distrust my VW dealer, but I don't want to be cavalier) Since I live in a moderately cold climate, I would only be using it in summer.
