Though none of my business, by the time one goes to the trouble of asking is a good bike is worth buying at a given price, that good bike, and deal will be gone. It is a good idea to develop an understand of
Vintage Bicycle Quality, a set of standards that applies to all vintage bicycles worth having, and then you will be prepared to strike when the iron is hot and before a guy like me scoops the deal.
Again, not sure of you level of understanding about old road bike quality, but I do hope this is a help.
