How to differentiate between modded and vanilla?

Hello,

I am trying to modify one of the vanilla cars, but even though I changed the name, the brand, and even the body style in the info.json file, the mod is overwriting the vanilla vehicle, such that I can't see the vanilla vehicle in the selection menu.

How to I keep both the vanilla and my variant of the car?

 

Did you change the name of the folder in the zip file? vehicles/this_name

 

Yup... Wait no... I only edited the ZIP......

Thanks, it works now,

 

No problem
