The best most comfortable ride I owned was a 1971 Buick Electra 225. 455 cu in, 25 gallon fuel tank, all the luxuries.......my college ride. It made many long distance 1 day hauls from Ames, IA to San Antonio, TX. Stops for fuel, food and relief. It had over a 400 mile range and would cruise effortlessly at 75 mph for days. It was even the puke avocado, army, olive drab green.
Not many modern rides have those capabilities.
