From what I've read about these things, the maintenance costs if they're used for anything but sitting in a parking lot are insane, especially in the civilian world. There's no established supply chain for special tools and spare parts like there are for normal, mass-market vehicles, so they have to pay through the nose and wait forever for them, or do without. Making this an especially strange purchase. Any cost saved on getting the vehicle will soon be eaten up by fuel and maintenance costs - I'm sure the gas mileage is terrible too.
