3 stars cause the game is great..... graphics, game play, its also great at sucking you in to the point you can't progress any further unless you spend real money. Which is fine I've dropped $20 on it. Its worth it. But the entire Tuner series is made to get your money. You have to increase car stars (rarity) in order to move on to the next race. But it's so expensive to do you run out of tokens to spend before you even get to 1 star. Either forcing you to play months maybe years or buy a pack.
