I hate to cast a sour note on a noble cause, but the environmental impact of biodiesel is not quite as rosy as all that. In addition to extra N02 emissions, it’s still typically mixed with sulfur and soot spewing diesel.

Now couple that with the fact that a 20 year old diesel Mark VII (not cadillac El Dorado) probably gets about 15-20 mpg, and the license plate looks less and less appropriate. I like the idea of making alternative fuels “cool” but it needs to be understood that this is more for show than effect.
