I've looked all over the internet but haven't found anything. I'm trying to make some cars addons, but I have no idea how to write entries for carvariations/vehicles.meta. I've tried studying .metas from vehicles that I have already installed, but they all vary in one way or another, so it's not much help. Could someone please point me in the right direction?

Whenever I add an addon vehicle, I simply take the .metas from the 303 add on car pack. If the car isnt in there, i simply get the same type of car that is in there.

For example: If I want to add a crown vic that isnt in there, I go in there, get a similar crown vic (If i want to add a 2008 unmarked, ill look and see if there is a 2008 unmarked in there) and then add those metas, and change the name to what i want it to be. 

Thats how i do it.

I used that pack for all my current addons, but some of the vehicles I want to add have no similar versions in that pack or I've already used their similar .meta files.
