Yeah, no. I don't just go around rating suggestions for no reason and leaving it as it is. I could've done that but instead, I went out of my way to respond to a suggestion as vague as yours whilst also supporting my rating with constructive feedback. You expect others to fully understand your suggestion when you throw around words such as indestructible and "title says it all" without even further clarifying what you actually want implemented.
Still, back to your suggestion:

Sure. For argument's sake, if implemented the car will have a perfectly fine visuals whilst still being prone to
actual vehicle damage(hp loss) from hitting a wall or getting shot at. You're still gonna have to go back to the gas station to get it
actually repaired, no?
