Makes your region discount apply to those cars from that region - but you lose it for your current region. Be warned, first switch is 100k, second is 500k third is 1mil or more. If you're trying to get all the cars in the game don't switch region until you've got all the cars from your current region.
The last time I checked my clock was at 72 hours and I still have a few cars to get. So you have a very long way to go![]()
