Replace the chain or not?
Recently got a 1983/84 Velosport Prestige. All components are in really good shape. Being new to vintage bikes I asked my LBS about chain replacement (in addition to all rubber) and they suggested I do it even though it is is good shape (has been soaked and cleaned). Looking for some feedback / suggestions.

If its in good shape, why would you replace it? Brake pads deteriorate whether they are used or not. Considering how critical they are, I would consider replacing them. But a chain that was lubed and did not rust, why replace it?

Even though the chain looks to be clean and in good shape, it is possible that there is enough wear causing the chain to "stretch". If a 12" section of chain has stretched more than 1/16th", then undue wear can/will be occurring to your gears. For more info check out Sheldon's site...

Inspect the chain not only for Sheldon's 1/2 percent elongation but also for misaligned rivets and frozen rollers.
