Dan,
I looked at the list of boats on this site, called "Our C-Dorys".
You can see it by clicking on that name in the menu at the top of the page.
The list can be sorted in various ways and I found a 2008 25' Cruiser with a production number of 273. Based on that, I would estimate that between 273 and 300 25's have been built by the new factory. Of that number, how many have been reported with core problems? Perhaps 5 to 10 is my guess.
Any boat can have problems, just try tossing some copper pennies, or copper wire clips into the bottom of an aluminum boat, add a little salt water and see what happens. Those two metals will make an electrolysis couple that will eat holes in the boats bottom.
If a 25 ft C-Dory fits your needs, buy one and then remove each screw or hatch that penetrates the deck or floor, squirt in some 4200 sealer, and reinsert the screw, or reseal the hatch. That should take care of the problem for your ownership lifetime. Bob(thataway), would recommend removing the core around the screw hole and filling with epoxy, then redrilling and inserting the screw. That is a better repair, and needed if the problem is severe, but just sealing with 4200 will be adequate preventive care, in my opinion.
No boat is going to be 100% perfect, so the new owner will need to spend some time doing maintenance each year.
I have heard of the Boston Whaler problem of the entire core becoming saturated with water, and I would not like to endure that, but the C-dory problems should never reach that stage. They are mostly small problems and easily fixed.
Good luck on your search.
