Normally you can't but there is a way. If you have unlocked GatMobile then it's work with all vehicles, and there is one more thing before you do all the thing.WAIT! You can change color of APC??!?!?!
If you try change vehicle collor, game may not respone or block that function.
So you must install {mod v1.2.} but there is a catch, you can't install it normally droping all files from (Extended customization) into game folder, because they may not working.
Instead you must drop it all into; [C:\...\Saints Row - The Third Remastered\cache]
There is no problem with files collision because game and mod hawe them diffrent, I also have one more hint better don't touch (heli files) folder just delete it.
So that is all steps to changes you want:
- Hop in the non_customizable vechicle you want to modify, and save it to your Base garage,
- Go get a customizabe vehicle like GatMobile,
- Drive it into a RimJob garage,
- Select garage,
- Highlight the non_customizable vehicle you want to edit,
- Back out of that menu,
- And now you can edit all the thing you want.
PS; Praise the mighty Poland! Żeby było śmieszniej posiadam prawdziwe szlachectwo.
