1. You didn't "buy" 2.
2. You have "reserved" 2.
3. Not without Tesla's express permission.
4. Which I've never seen them give.
You cannot. You would need to buy car, then resell it.
I was told by Tesla that they would only give you permission to transfer you reservation to an immediate family member. The process will be done during the config period and not before. You can buy it and resale the vehicle. I have heard of people considering that option but it sound a bit risky. If done correctly I can see how you can make a small profit, but highly risky. You could get stuck with a new car.. or worst burned by a buyer.
If I remember correctly, isn't there stipulation with tax credit/state rebate programs regarding resell?
If you resell you won't get the tax credit and the buyer doesn't get it either.
