Even in the US the sales of the Honda Civic GX are horrible and I think it has been out of production for a few years due to poor sales. It is gas only, so cannot travel more than 150-200 miles from its home base where gas might be available. There are very few CNG stations open to the public, so the main buyers have been local and state governments who can fill up on their own stations. There are some of these owned by private citizens too, and their experiences, other than the availability of the fuel, are quite good.
