After 4 Bronco's since 1977, I can say I have never scratched a dash, and can't imagine doing it. But being a semi-neat freak, the usual potential for scratches would be keys swinging in the ignition, which is why I only used the single ignition key when in use. I could imagine certain Bronco's being used in more fun environments getting scratched, but the rest of the rig would likely match.
When people want to touch a surface, I use the statement regarding exterior car paint and interior house paint on the walls, "If you don't touch it (F it up,) then I don't have to fix it.;D
