My express concern is I show up and I owe $88k. I certainly do not want to wire them $88k unless i'm satisfied the correct options are installed and that everything works properly - and the vehicle charges etc.
I expect an hour of picking through the options and features and making sure they work, and that the paint is in pristine condition, as is the underside of the vehicle, nothing squeaks or rattles on a test drive, bluetooth syncs, music plays, maps display, EAP works, doors open - etc. Lets say I'm standing there and EAP does not work properly. They have $88k of my money if I wire - who cares if they fix it or not. I don't wan to be in a situation where I"m forced to take delivery and then deal with production defects as warranty items.
I want to charge $10,000 to get the airline miles and bonus miles for the quarter - then bring them a bank cashiers check for the balance. It's the only leverage I'll ever have. . . plus I loose warranty coverage for the time the car is being finally assembly under warranty . . .
