Restoring Your Car On Jobs
When you start to take damage while on a job/mission/delivery and you can't afford to take any more, click on the start menu and go to options. Then click on the "graphic preferences" section, then go to "cars". After that click on "car damage" and set it to "off". You will notice that your car will be fully restored, and after that turn the damage back on and repeat it if you need your car restored again.
