I'm very close to pulling the trigger on my first used DB. It's aluminum from a well known manufacturer w a galvanized baker trailer. The boat and trailer are 9 years old but look to be in good shape. My wife keeps saying "maybe you should just buy a new boat instead of a really old one". I'd rather save the extra $6000. My understanding is that as long as it's not beat up, an aluminum DB will last forever. A good trailer will also last a long time with a little maintenance. So, what do you consider an "old" DB? What would u predict would start falling apart first? Or do they really last forever? And how does age affect resale value?
