No Damage to your car.
If you ever get tired of seeing your car with dents, scratches, etc., with a risk of it exploding when you need it most, then I have one request for a new gameplay mod. Just a simple "No Damage" mod. With it, you can crash and trash anything, and NOT get any damage at all on your car. Not even a scratch. I used to have a couple of games for the PlayStation2, like "Need for Speed: Most Wanted," which came with the "No Damage" option by default. I would love to see that in GTA V.
