Well How Long Do You Think One Will Last?
I have no real idea, but suspect the electrical portion would be easier to keep in like new condition with relatively minor repairs and the combustion part would last more miles than in a conventional car due to a lower rate of use.
It's not just about economics either. It's about taking responsibility for your own actions. Now while I realize many here don't care about how much they pollute or how much greenhouse gases they pump out, others do.
