Sounded good until i gave it some thought. Because the car is missing some speakers, they shut down the assembly line, or dont make those cars. Assume they just dont make those cars. In the meantime with a just in time supply chain they have 99.44% of a significant number of cars. They then tell the boat that is supposed to have those cars to keep sailing at say 75% capacity. Oh, and we will pay you later.
Then when the cars are finally done, and the ship is on the other side of the planet they have to find another ship. Well that one can only handle half the cars and cost twice as much.
Should i go on? Because they didnt want the parts sitting around they used the parts for your car to build someone elses car that didnt have the radio. Now they have the chip for the radio, but not for the left front TPMS. Back to the drawing board, because they are making cars for third wild countries that dont need TPMS, but need the better radio.
Dont be upset at the delay your salesman says. Remember you told the factory not to build them until they are properly supplied.
