The 4xe is very intriguing to me. I have a couple of questions. Not ever have owned a hybrid vehicle, what would the manufacturers warranty be on a vehicle like the 4xe? Second, I live in a rural area in northern Michigan and work at home. The brewery, bank, post office, gas station, and store are within 5 miles of my home and there are 1000's of acres with off-road trails right behind my house. If owning a 4xe, I could see myself never needing to use the ICE. My concern would be having the gas in the tank going unused for a long period of time and ultimately going bad. Is this a valid concern?
