Quote: If you have reached a certain experience level in the game where you CAN level up then you MUST purchase the next level upgrade or your experience will no longer accumulate at any high rate. This means that if you have enough experience you have to level up.

I imagine that prolly along the lines of lvl 6~10 it'll cut you off. Not real sure though, but I feel bad for those who get maxed out while offline and still get races before they log in again.
