i honestly have no idea how to achieve it :)
spawn command does work well if i use the preset file.
Its the destroying part that worries me,as what will remove these from the server or do they get removed on server reboot ?

Cars may be deleted when the server reboots if the current car population is above the max population calculated by the modularcar.population cvar. It depends on map size, so for example a 4k map with population 3 might allow 20 cars for example (fake number). However, I found that it doesn't consistently seem to be the case because at times I spawn in hundreds of cars and none get deleted when loading the save.
