So I really want a Tesla Model S, have to get some expenses paid first, but may be ready to order in 2014. I have some thoughts about owning a Tesla (or any EV for that matter). Please comment or correct my statements below. I'm not disrespecting EV ownership in the least, I just want to know what I'd be getting into...
1) Once the 8-year warranty on a Tesla (and also the warranty on a Leaf, for example) is over, the car has an effective value of zero.
2) Since the batteries cannot be upgraded (Tesla and Leaf) or replaced, once they are dead, the car is dead.
3) Unlike a hybrid or gasoline car, the end of the battery warranty period is likely the end-of-life for the vehicle.
4) The battery range will decline over the life of the warranty, possibly leaving you at the end with much reduced range.
If my assumptions are correct, then you must replace any EV at the end of its battery warranty. This means that for the $30K Leaf and the $90K Tesla, you're deciding to pay $4K or $10K per year to own the car for 10 years (I through in an extra $1K per year for financing charges, electrical costs, fudge factor).
No flames, please. I'm just a good businessman who wants to know his costs. After a couple of car fiascos, I need pretty solid reasoning to drop almost $100K on a Model S. Any input will be greatly appreciated.
