can we fix or repair our clothing, containers, vehicles, etc?
One cannot repair simple items, like clothing or weapons, at least for now. Items like vehicles, that are made of other items can be repaired by being disassembled, and the parts with lowest Condition replaced. Let's say you have a Shopping Cart - you can take it apart and replace the most broken wheel with a better one that you have found. That will enhance the overall Condition of your cart. Just keep in mind you will need a tool and knowledge in Mechanics to to that.
