Red / white Plates

all has to do with a dealer optimizing his cash flow,
If they need to a dealer can get white plates within a few days but they prefer to run this scam whereby the bugger around for a month or two because when the get the car registered, only then do they have to pay the supplier.
Why register it immediately? after all they have your cash in the bank and have not yet paid for the car.
If they can string you along for a while with some BS story, its all money for them , if they can feed you some BS that the red plates have run, out even more cash, its called laughing all the way to the bank,
