Evinrude Rooney Lakester (1970)

Evinrude Rooney Lakester — Boat slipped into car body
You back this dune buggy down to the water’s edge and suddently it gives birth to a 14-foot fiberglass boat. After the cruise or waterskiing, when you’re back ashore, an electric winch hauls the boat aboard its wheeled partner. Dune buggy and boat are powered by same 50-hp outboard motor. The buggy has standard Volkswagen running gear and an infinitely variable hydrostatic gearbox of the type used on high-power garden tractors. The prototype, a brilliant orange and pearlescent model, appeared at the San Francisco Boat show in January 1970. Created by Brooks Stevens, the Lakester is expected to sell for around $2,500 when it becomes available.
