I have an 07 and it has greenwood XL which is a CCA (A=arsenic) marine plywood that is guaranteed not to rot. They started using in it the late 90s, but not sure when it was fully phased in. You can call GW customer service and they can tell you about your model and year. The transom caps have been a weak point. Mine has a little corrosion, but I keep it sealed and coated lightly with LPS 3 and since I have had the boat (9 years) it has been fine. If the boat has maintenance records for the generator and engines the mechanical items are easy enough to fix. A good survey will let you know most issues. My boat has been great!
