Duplicating car?

Didn't find a thread of this so hopefully not a repost

So, how can I duplicate for example the Grand Marshal so I would have 2 of them?
(No, this is not about spawning an AI)
I have a few textures I've made and every Grand Marshal has the same texture, how can I create two different Grand Marshals so that they have different textures?
I tried duplicating the fullsize folder and renaming it something else, but the game crashes when I'm spawning it. (Might have been a retarded idea)

 

Bump, I'd really appreciate if someone could tell me

 

Spawning Vehicles

 

That's not what I meant, I meant more likely to "add new car to the game"
So that I'll have 2 DIFFERENT Gavrils with DIFFERENT textures

 

he just explained how you do that...

i guess you could go into the vehicles folder and ctrl+c - ctrl+v and just rename it.

 

I tried it but it crashes my game when I spawn it

 

You may have to go into the copied/renamed folder, and go through all of the .Jbeam files and rename them from being named the same as well, otherwise the game may be trying to pull the information for the new car from multiple locations at once and causing the crash.

IE:
{
"fullsize_engine": {
"information":{
"authors":"gabester",
"name":"Gavril Grand Marshal 4.5L V8 Engine",
}

change "fullsize_engine" to "fullsize_engine-NEW"

It may be a horrible thing, as you may also need to go through and change MANY other aspects to actually 'create' a new vehicle, in other words find every reference of 'fullsize' and alter it to the new name of the new duped grand marshall.
