You drive to the blue shop in roaming mode.
Look for it. You can buy it if you untie it. You can't buy it until you untie it.
Unless you cheat.
But I have to tell you that the car you bought is worse than the car you got.
Be mentally prepared. I suggest that you don't put on record before the game.
If you don't draw it, compare it until you draw it.
It takes some effort, but we can get all their cars.
