Your Garage is where 98% of the game takes place in Car Mechanic Simulator 2015. Knowing where to find things, what you can find, and what you can do will help you get started.
On your desk you'll find the Phone, the Computer, and a Camera. The phone is your key to jobs. This is how you'll make all of your money in the first stages of the game.
The computer is used to buy parts for jobs and later for cars you purchase at auction. When using the computer you'll find that there is a general parts shop, rim shop, and body shop. In addition there is also a special shop for the Maluch, which is a vehicle added by one of the DLC. Tunerz Paradise is a mod parts shop where you can get special parts to trick out cars when you purchase them from auction.
The camera lets you take screenshots. It is actually quite versatile and will help to make sure that your screenshot comes out clear with no cursor or selection lines. You can also pan, zoom, and tilt the camera.
