Add on cars using zap hosting

Hey guys
Do you add addon cars the same way you add replacer cars using zap hosting?
I dont want to replace any cars just add new ones.
Any help would be great.

Yes?! Your hosting has nothing to do with the way you do things with the FiveM server

Sorry i think i worded it wrong. So i watched tuts and videos about how to replace vehicles using filezilla ect, but nothing on how tk straight up add a new vehicle
