Hey i think it would be a cool idea if there was an option to save a vehicle with the damage and aging on an engine
There is already a way to do this, should be somewhere in the radial menu (I don't know where it would be after the radial menu changed). Only two problems is that, for one, it opens all the doors when you load a previously saved vehicle, and secondly, this does not save permanently, and as soon as you change maps or replace the car it will no longer be saved. It would be nice to see a better version of this feature, since it is already in existence, just needs a bit of refining.
