Not sure if the mechanics have changed to where you can't open and close doors of a vehicle, but that would be nice for vehicles like cargo trucks, the cargobob, and the titan like some menus used to allow you to do. Being able to modify specific modifications of a car would be nice, but I could see given all of the new variations that it would be a bit difficult. It would be at least nice to be able to save car configurations and name them like creating an instance of a lowrider with x color, y modifcations, and so on that you either found (like the pre-modded ones in certain missions) or ones you have customized yourself.
