Why do some cars rust and others don’t? I realise that every car will probably develop rust at some stage but excluding environmental factor, why does it happen to some more quickly that others?
Cheaper materials?
Improperly treated materials?
Cheap paint used?

Paint is the coat with less impact on rusting. The metal goes through a lot of processes to prevent rust like electrophoresis beneath enamel and clearcoat and a wax coat on the underbody. Cheaping out on these processes will be visible on the long run. It’s common to use salt on the roads to melt the ice in northern europe, all german cars get those processes right.
