I bought my 2000 C-310 almost 4 years ago, and paid $10K+ more than the asking price on this one. The batteries were not caught in the survey, as everything worked great on test sail day. They were shot. OK - 8 years, not bad, not terribly expensive ($350). The sails were original, and I replaced them last year ($3300). The surveyor was excellent, but so was the boat. The previous owner kept it in pristine order (head was never used!), and though not perfect, it was in darn nice shape.
Prices vary from east to west coast. On the west coast, we pay a little more, reportedly. Stories as to why mention shipping costs (from Florida now for Catalinas), climate (supposedly, boats fare better here in Puget Sound), and market values. The prices HAVE come down since I bought, so prices appear similar now.
Mine came with roller furling jib and Dutchman main (full batten), Garmin GPS, full set of cushions, a dodger, an Autoprop ($$$), and was ready to sail. Had to bottom paint two years ago, and I added a bimini and hydronic heat since acquiring her. We have sailed her bunches, and motored approximately 100 hours per year. My damper plate is probably shot (making noises), and the shaft seal probably should be replaced, but I am completely satisfied and pleased with my 310.
I believe you will be too, assuming no major issues. However, even THOSE can be addressed in the sales process. Make your offer contingent on a survey and mechanical assessment. Hire your own experts (get references), and if something comes up, DON'T hesitate to counter offer a price lower by the amount to fix the discrepancies. Be prepared to walk away, but also be aware the current owner KNOWS what the boat's issues are (if any). He is hoping you won't find them, and you may still miss one or two.
In the end, you will have the boat you want, whether it is this one or one like it. Go BOLDLY! $60K is a lot of money for most anyone, so it's OK to be tough.
My 2 cents.
