The Jeep is a CJ-5 of the early-1970's. The brown car belonging to the businessman is a 1975-76 Ford LTD. The motor home is a Winnebago(not sure of the model, although I have a few guesses). The station wagon is also a 1975-76 full-size Ford, but it's more than likley a Ranch Wagon. The white car below that is a Chevrolet Vega. I'll pick the others later on.
