Get a job. Note that with every promotion, you will get a nicer car. To get promotions and create a garage, first create at least a 6x12 room. This will fit two small cars. SUVs and Hummers are larger. Create several Gnomes with the desk that has the tools on it. Make sure that the car you want comes to your house, but that nobody gets in the car. Enable the move_objects on code and enter buy mode. Use the hand to grab the car, and rotate it into your garage. Make sure there is an object directly in front of the car(s) that is not a gnome. Click the disk icon to save the game. Replace the item blocking the cars with the gnomes. After that, save the game by exiting to the neighborhood. -Get back to playing the house. Save by using the disk icon again.
