Some of the extended family fitted out a bus and went for a drive. After 5 years they made it to Darwin and checked into a caravan park for a couple of years.
They noticed a pattern with some of the vans/station wagons (some had been repaired with panels from the wreckers, matching the paint was not a priority)
These cars were undergoing a “deep clean” and polish before their next trip around Australia with the new “owners” (there were doubts that paperwork was ever transferred)
Repeated every 12 months
