I am scheduled to take delivery on my model 3 on 11/17. On mytesla page it notes I owe around $1,800 (not financed) and the rest ($51,000) will be a loan thru credit union. Do I need to pay the $1,800 ahead of time or if I pay on delivery, how do I pay it? Via a bank check made out to who? Also I am thinking now that I want my loan to be $50,000 and I pay $2,800 at closing. Does mytesla page need to be updated to reflect that or can I just bring a check for a bigger amount and the loan payment will be $1000 less.
