You need to explain more about how and why your saving the vehicles.
If you always want the server to have the same vehicles just use addstaticvehicle in ongamemodeinit.

If its cause you want players to be able to save vehicles, then just add their name to the line that you save them with, so that the player can spawn the vehicle when they want to.

If you are having issues you can always just download one of the already existing vehicle scripts.
