Hello everybody.
I downloaded the demo today and drove a few laps in single player and multiplayer mode.
Now I wonder how I can switch between the 3 cars in single player mode. In multiplayer this is possible without any problems.
Did I miss something?
Thank you in advance.

Garage menu accessed over shift+P is identical in both multiplayer and singleplayer modes - just click on "Car" ("Wagen" auf deutsch) in that menu to access car selection menu.

Thank you. I will try it.
In multiplayer, I was shown the option in the box at the bottom right. Not in single player.

Sounds weird. Maybe make some screenshots,so we can see what's missing.

Thank you for participating. Figured out how it works by now.
