Also old bikes are old. Even if mileage is low the rubber/plastic is fragile if not already cracked. Fuel and oil lines/reservoir are clogged and or falling apart. Brake pads are stiff ineffective. Tires are usually shot. And after you fix all of that stuff(you must fix otherwise you are very unsafe) at significant co$t, you still have an old bike with other things giving problems.Don't pick a bike just because it was "it" 40 years ago. Old bikes are like old muscle cars: they're not anywhere near as good as people think they remember. Modern bikes are better-engineered, better-built and better to ride and own.
