the new update made me want to have a way to repair parts in remote areas. It would be cool to have a system like my summer car or car mechanic sim. getting out and unscrewing bolts and repairing parts of the suspension would be so cool. maybe all of the upgrades could be applied manually as well. I think the ability to do the repairs manually would add to the feeling of ownership of the vehicles. I don't know if this would even be possible but I think many people would enjoy it. It could also have a toggle for the more casual people.
