When I was a young lad in Bulawayo, then Southern Rhodesia, a weekend's jaunt was to transport new cars from Port Elizabeth to the dealer in town; and get paid for it.
Friday night on the train to Joberg. Then a connection to P E and be there at lunchtime. You would then take charge of anything from a big Chevrolet/Ford/Plymouth/AustinA90/Worsley6 and proceed to drive these in convoy up north. Another night stop in Joberg and Sunday afternoon these dust laden, race proven cars would arrive at their respective dealers to have their pre-sale service, plus other corrections, before the purchaser saw it.
Couth dealers, like Jaguar and Bristol(Glasby's Garage) would have their cars shipped up by rail.
