Difficult nav and difficult terrain are two different things. If they just eliminated GPS and went with roadbook only, that would be cool, and would be the same difficulty on vintage or modern vehicle. More difficult terrain needs to be in a different event, not M1K. As long as GPS navigation is allowed, it's not a real rally.
