The Good (Bad) Old Days
I repeat really my last bit, "I had one of these brand new in 1972 for my 18th Birthday starting college, it was my pride and joy, so it's a purely sentimental trip for me with no expectation that any restoration will ever turn it into a practical machine or even medium touring bike."
Also, I cycled on a similar secondhand Raleigh (which I abandoned in Rome) all through Greece, Corfu and in Italy in the 1970s. A good work out. Since then I've stuck to Treks in the mid price range. There is no comparison!
Vintage bicycles are just vanity projects for hobbyists or perhaps the odd person who had one "in the day" and has time and personal interest enough to idle their time away fixing it up. For real cycling enjoyment on crowded roads as they are today (that's an important consideration) a modern bicycle wins in every way.
