if you get all gold medals on a license test you win a car. *if you don't get all gold medals on the first try, then save and finish getting all golds for a license test later on, do you still win a car?

It doesn't matter how many times you try.
As long as you get all gold at some stage you will be rewarded with a cool car. ;)

Drool at the sight of these cars cause for most of them this is the only way to get them!
