1. Battery life expectancy and replacement value ( $$$$ deduction).
2. Huge rebate at the purchase time ($$$$ deduction)
3. Maintenance and/or unpopularity issue ($$$$ deduction).
I can see some horrified faces already!
I read somewhere that the batteries are only good for so many miles which IIRC worked out to be average driving of 3-4 years.The replacement cost of the batteries are about $25K so more than 1/2 the price of the car.I doubt seriously any of them will get any trade in if the battery at a cost of $25K isn’t replaced before taking it in.
Don't worry-by the time trade-in time comes I'm sure the government will have figured out some way for taxpayers to subsidize their loss too.
