1. Get a relatively cheap used diesel car (rabbit, or some VW TDI)
2. Aeromod the beast (a la basjoos except with kind for foam fiberglass composite)
3. Set it up to run off biodiesel
4. Laugh all the way to the bank when gas prices go through the roof. XD
that would be more than enough for one year I'd think
edit: just realized this thread was for 2010... meh only one year off.
