To buy a car select it in the list and press the buy button.
Make sure you have no car outside of your garage and be sure you took enough money with you. After you purchased your new car you will recieve a yellow code with 4 letters. As example we take "asdf".
To unlock your car you will have to enter the keycode. To do this press T and write "/key asdf" without " to unlock the car. We recommend to write this code down.
