How to create vehicle versions (D15 i6, D15v8 etc)

Hi guys, just a simple question that I couldn't readily find an answer to on the wiki pages.

I'm playing with the settings on some of the cars and wanted to save them as something else, how can I do this?

 

In game, press CTRL+W to choose parts individually. Press CTRL+E, and choose a vehicle and a variation to get the stock versions

 

Select the parts you want to save and press save.


Name it and press save.

 

Thank you
