Right now I think repairing vehicles is a bit too easy. So how about when repairing a vehicle component you need some of whatever material it’s made of. metal, plastic, glass, or whatever.
Also, removing destroyed components should return a small amount of whatever material that component is made out of.
STOP BREAKING ALL MY- oh wait no, that’s perfectly reasonable. XD
I’m still waiting for the ‘gone’ addition to vehicle damage. XD
So long as cosmetic (light green, maybe yellow) can be fixed without extra material, no problem from my perspective. Same general idea as clothing: you can buff out scratches, push dings back out, etc, but a hole’ll need patch material.
