The biggest Pro for vintage bikes is the clean diminutive look, especially pretty if lugged. I hate the way most current bikes look with weird oval shaped oversized down (and other) tubes, diameters so large that it could be used as sewer pipe for a small city, extensive use of plastics and worst of all, the name of the manuf. plastered in 3+" high letters, extracting lifelong free advertising from you on top of exorbitant prices. To me, a lugged bike is a proper bike. It is like drinking champagne from a proper champagne flute vs. drinking the same from a disposable polystyrene cup.
