Yes indeed.
By the time you replace wheels, tires, tubes, brakes, cables (might as well do levers too at this point that match the leverage ratio of the new brakes) and fenders you've probably put more money into the bike than you could spend on a new bike -and ruined the whole character, feel, and value of a "vintage bike" in the process. But that is a personal decision.
My own current Raleigh:



But here's the catch. I'm retired, I do all my own mechanical work
(car as well as bicycle), and I'm not really all that tightly wrapped.
So draw your own conclusions in your own case. I will say that the
Retro Raleigh Post Apocalyptic Transportation Module has served
me well and is much more fun than going to Trader Joe's in a car.
While not theft proof, there is usually something shinier parked
next to me in the rack, so thus far it has been there for the return
trip.
But that is a personal decision
Is this a great country or what?
