my dad found an old fender coronado 1 bass at a pawn shop, and he says its in ok condition, the usual worn finish on a few spots, and some bumps and dings, but nothin too serious. there asking either $500 or $600 dollars and he thinks he could get it for maybe $400 or $450. we'd have to buy case for it and pay shipping through ebay. so is it worth it? how much are these goin for on the vintage market?
