Add multiple vehicles into one game?

Hi, i am trying to find out how to add multiple cars into a single game. So i could pick them up with forklifts, etc. I got into the editor but i have no clue what to do from their. Please help!

 

No need for the bold letters... but look in the wiki there is info in there

 

All you need to do is open the menu while your in game, open up the vehicle tab and add a new vehicle. Then hit tab and change the vehicle you've spawned.
