Anyway .. definitely a repost. Ford made them as fleets for government use and you see them pop up on eBay every now and again. The CNG tank only gets you ~100 miles I heard, plus I don't know of any CNG station around here. A few CEGers have bought them and flat out removed the system to get their trunk space back.
It's a beautiful, albeit failed, execution for an alternative hybrid system.
