I think this may be the best post of this thread. Vanity is silly, but it also makes the bass world thrive. If we didn't have color preferences, body shape preferences, wood preferences, etc. that are largely related to the visual aspects of the instrument, there wouldn't be a market for all the different brands, models and price points that we currently enjoy.
To me the "a tort pickguard is always the best choice" is far more of an issue than a road worn finish. To my eye, tort only works of a very small range of finishes. (sunburst, natural, white) All basses can get dents and dings over time, and when and how they happened isn't really relevant to the instrument's current appearance.
I don't want to get sucked back into this, since I know I'm bordering on invoking the wrath of the TB hive here, but there's "silly" and then there's "SILLY". A roadworn bass, to me, doesn't look silly - it's a bass that has been used / abused and looks it. A hello Kitty bass -THAT looks silly. But a person buying anything that is built to look not-new... That's a different kind silly to me. And yes, this includes expensive basses like Fender Custom shop or, what I recently saw at Bass San Diego - Nash basses:

I have no doubt some folks would love these - folks on this thread, I suspect. It is there right to do so, just as it is my (and a few other folks on this thread) have the right to roll my eyes.
