I set the spawn of CH47 to false in the config and also didnt give it a permission.
Is it possible to add the ability that it disappears from the menu list then?
If players type /buy they still have it there. Yes, they can't buy it then. But it would be great if it just wouldnt appear at all.
Thank you.

Yeah that's something I need to re-write as it's hard coded atm...  maybe next release

Is this fixed now?
Are we able to decide which vehicles can be bought and which not?

First delete the lang files (VehicleLicense.json) in oxide\lang\en, oxide\lang\fr and oxide\lang\de, then delete the lines you don't want to appear from the .cs file under the Localization part.

That may work but after I have to rewrite the lang files again to put in the lines I individually had there to fit to my server.
And often a new update of this plugin causes that the lang files are overwritten again. This is really annoying.
So I'm still hoping there will come an option soon to deactivate certain vehicles and make them disappear in the menu.

Same problem here,
i always forget to hide lines for vehicles that are not for sale.

Is it possible to NOT show them if i set "purchasable" to "false"?

"Chinook": {
      "name": "Chinook",
      "prefab": "assets/prefabs/npc/ch47/ch47.entity.prefab",
      "purchasable": false,
      "price": 30000,
      "cooldownToSpawn": 3000,
      "distanceToSpawn": 25,
      "commands": [
        "chinook",
        "ch47"
      ]
    }  ​

Open the .cs file on a text editor and remove lines 817, 825, 833, 868, 876, 884, 919, 927 and 935.
