Your price quote is way off as has been pointed out. At the moment I have to question your statement about battery replacement. In addition, without knowing how much batteries cost to replace, I can't get much meaning out of that. Finally, there are other maintenence costs that won't be a part of ev ownership. things like oil changes, air filter changes, spark plugs, wires, injectors, fuel filters. You'll never have to replace your radiator or water pump. The list goes on. No belts, no pulleys, no timing chain, no starter, no alternator, no transmission.
