The game needs a option for you to customize all vehicles that can use specific add-ons or customizations. It’s really annoying to go through all owned vehicles and customize them one by one.
Such as, if owned vehicles can use specific add on or customization, you can customize all those vehicles at once.
I don’t think this would work, as every car you have will probably have a different scraps total. It’s the way the scrap system works (kind of hard to sum up).
but at least make it so you can paint all the cars at once and put the material
or upgrade all cars that have enough at once
