In 1973 a friend and I drive a P1800 that had a rally prepped engine and suspension including 5 point belts on a 8 week 8k mile round trip from the Midwest to skiing the Rockies, then up and down the West Coast, including south of Ensenada,Mexico and then circuitously back home. Its top speed (in Nevada with no speed limits) at the time was aprox 120.
