What could be better than filling up for $6/tank--and right in your own garage, to boot? While residents in CA and NY currently have first dibs on buying the GX, stations abound for re-fueling once you have a natural gas car (yes, conversions are available). For example, even out here in rural PA, we have a natural gas filling station within 30 miles of our home. The infrastructure is there for natural gas and propane vehicles to take off. After all, fleets have been using them for years. And if Honda's GX is anything to show what's in store for us, the upcoming years' AFVs will have us all singing their praises.
