I bought my GX 2 months ago and I LOVE this thing!!! You should see the smile on my face when I fill up my car and the total on the pump shows $4.50!!!
Utah has quite a few public fill up stations, plus I totally love that I can install a pump at my house and fill up off my own Natural Gas supply. I haven't done this yet, but how cool is that???
Natural Gas prices in my state are controlled by the State Public Service Commision, so theres no day to day (or even week to week) price volatility. The price set for the entire state is .78 cents a gallon at the public fill stations.
Oh yeah, I'm LOVING it!!!
