Sorry Tesla, or any other company for that matter, will not allow you to drop your payment if you drive less. That's like leasing an apartment room and asking for a discount because you decided to sleep over your girlfriends place more.
As for lease swap, unlike the apt rental scenario above, most, if not all banks, allow you to transfer the lease to another person. There are some restrictions that vary from bank to bank, such as the new person has to live in the same state you do, but basically you and the new lessee fill out an application or credit app, to see if they will qualify. If they are approved, you can transfer the car over to them.
Yes, I'm sure you have lots of questions forming now...
1. What about my deposit.
What about it.... it's gone.
2. Can I ask the new buyer to pay me back
Yup.... you can even pay him to take your car too (holy moley). It's all negotiable. Bank will not care what you guys negotiate. They only care about someone finishing the contract.
3. Can the payment be lowered
Again.. nope. It's the same payment and terms. New lessee just takes over what you already agreed to. So if you got a killer deal on a lease because of whatever reason (i.e. I know the right people, put a big ass deposit down, I am elon musk, etc), then that is what the new lessee will pay. Unfortunately tesla does not bargain so most likely potential lessee can get the same deal as you, but they could potentially save on the initial deposit and any remaining time on annual DMV registration.
3. What happens if he doesn't pay
Depends on the bank, you may still be on the hook or they may release you
4. Damages or over mileage
Off the hook for both.
5. Wait.. I'm under
Benefit would go to new lessee.
5. Wow this is a great idea, maybe I should think about this as a start up....
too late
