We have cars that can be damaged/destroyed and we have repair kits that can make these vehicles roadworthy again and again. It's awesome, but I might have an idea that can involve our vehicles more into surviving the apocalypse with us.
It's a bit absurd that fiddling under the hood in the middle of nowhere can repair the whole vehicle (engine and body) under seconds. Repair kits are good but how about we make them into repairing only the engine (restoring the health of the car)?
For repairing the body and replacing doors we should park our vehicle at our Base and access the given parking space to make body repairs manually for parts/materials (like we could in the first game but without the automatic vehicle repairs during the night).
Having an Auto shop (and someone with the Automechanics skill) or the Mechanics group as allies would make these repairs free.
Edit: We could also salvage unwanted vehicles the same way to get parts/materials by doing so. Having an Auto shop (and someone with the Automechanics skill) or the Mechanics group as allies would grant us more parts/materials.
