The reason it would not be showing a difference in payment, is because your drive offs would remain the same. "Drive offs" do not = "Down payment". They are not the same.
"Drive offs" INCLUDE down payment (on a lease that is called cap cost reduction), AND any other monies needed to leave with the car... like taxes, title, license, document fees, first months payment etc.
The reason your lease would not be changing online with 100 down or 2500 down is because that 2500 is going toward your drive offs, which in california are likely going to be around 2300-2700 or so, give or take, depending on which tesla you are getting.
Since you already paid 2500, you likely wont need to come in with much cash to leave with the car on delivery day. If you cancelled and re ordered with a 100 deposit, when you picked up the car, you would then need to come up with the money for those things above (likely around 2500 or so). IF you didnt want to pay that and just wanted to "roll all that in" you would not even be having the same payment you have been quoted now... if they even allowed it.[/QUOTE
