I played several Classic 50s and Roadworns in stores, they are nice for the price. I love the feel of the roadworns, I did a P bass taste test in a store once and found the Roadworn I was using felt better and sounded better (IMO) than the others I tried - including a Classic, a Highway One, a Squier Classic Vibe, and even my own 2008 American Standard. My American Standard was stolen shortly after, and I really did not want the Fiesta Red Roadworn, despite how awesome it felt and sounded, so I got them to bring in a Sunburst model. It left me feeling "meh." An opportunity came up to buy a '57 AVRI sight unseen, and I went with my gut and bought it, knowing I could re-sell it for what I paid if it didn't work out. It is awesome too - and less than $1000. Pretty much the same awesomeness of tone that the Fiesta Red Roadworn I'd tried had, different feel due to the neck not being worn. I liked the worn neck. My AVRI is ash, not Alder... does that matter? I don't think so.
Don't know if Nitro vs Poly really makes that big of a difference to me, for some it does.
All in all I'd love to have my stolen American Standard back. Black on black with maple... mmmm MM! For a brief period I had a 2010 model that I returned when I got the AVRI. The AVRI kicked butt over the particular 2010 model I had, but my 2008 was great.
Every P bass will sound like a P bass, and every one will sound subtly different and play different. You have to play them, and judge for yourself, really. They're all individuals, and only you can judge whether the individual one you have is worth the asking price.
Having said that, the Classic 50s tend to be great bargains, but so too are used AVRIs...
