I'm considering buying a car, but I don't want a cent of my money to, however indirectly, go to the mideast. I was looking into several alternative fuels. It seems the infrastructure to support most of these fuels is lacking. I did find one fuel--CNG compressed natural gas. It seems there are fueling stations across the country, as well home fueling options available. I was thinking of either buying a GMC Sierra, or having another American car retrofitted to use CNG. I was hoping that some members here, also sick of supporting the mideast oil structure have experience with CNG...
