I have a 76 C-27 w/ A4 and I can't complain.
Rob is right, check very carefully for areas where the deck is soft or spongy. I had to replace my foredeck last April and it was not cheap! Also you want to check around the windows, interior rigging mounts, stanchions, bow pulpit, stern railing, and along the jib traveler, along both sides for evidence of leaks. The leaks will be easy enough to fix but if you do see evidence of leaking then you need to be even more mindful of possible dry rot in the deck and bulkheads. Look at the gas tank and check around the plate where the gauge sensor and vent tube mount and make sure you have a good seal there. Also, during sea trial be sure to run the engine for a while and watch engine temp. I am currently dealing with that issue myself. All in all, if you give it a good look over and the surveyor gives it a clean bill of health I don't think you will be disappointed. Regards,Lysle
