I've owned a 1970 Fender Precision for the last 27 years. It's a working, gigging instrument that looks its age but has been well cared for.
Does it play nicely, feel good and look cool? Yes it does, and I love it.
Would I go out of my way to buy another one? Not really, given the cost nowadays.
It is very good, and it's a vintage bass, but I wouldn't say it's automatically good just because it's a vintage bass, or that other, newer, basses aren't equally good in their own way.
