Citrus--
The compressed natural gas Civic (Civic GX) has been available for awhile (at least in California). It is a near-zero emission vehicle and is allowed in the HOV lanes in California with one passenger (plus free bridge tolls during commutes). Because of the clean burning engines, it is supposed to last forever....well nearly, anyway. Fuelmaker was supposed to make an "at home" refueling device so you could fill up at home (at lower therm prices), but that hasn't happened yet...If you could fill up at home the equivalent gallon of gasoline cost would be about 90 cents per "gallon." Otherwise, you are stuck with limited re-fueling stations at about $1.70 cents per "gallon." One drawback (besides the limited fueling stations) is that you can only go about 200 miles per "tankful." Cost for the CNG Civic new is about 22K (plus tax, blah, blah, blah).
During my recent car buying decision, I was deliberating between the CNG and the Insight. I decided on the Insight because I found one used with low mileage, and my wife wanted the Insight--which is always a determining factor.... :roll: I was "this" far away from buying the Civic GX because I like my cars to last...There was no question about the Civic GX engine lasting/trouble free....Time will tell if I made the right decision....
