Defever made a lot of good boats. You genrally can't win the ugly boatb contest with them. Being a 1990 boat may present problems that are related to the period of time it was built and the age of the boat and less a refelction on the builder and more on the past owner(s). Our boat is a 1991 sailboat so while not of similar type the age presents problems that are hard to predict without a detailed survey. A lot of things that may have been built right the first time don't stand up to almost 20 years of age and use. You will have things to tend to. Perhaps many small things and maybe a few medium sized things. They generally don't show up in perfect condition with this much age. If there was any neglect it will be hard to hide in a survey. Long periods of sitting in a slip does terrible things to engines.
