Answer me this. Why all the BU's for sale?

No harm meant and I don't want to start a war. And to help you understand why this ? arised.... I am trying to convince the wife to let me purchase a new boat, whether brand new or w/i 3 yrs or so. I have narrowed my search to either a newer Supra or Malibu. I watch the classifieds pretty close and can't help but notice.... This is prime season, why all the Malibu's up for sale? I can understand a few here or there -- but go check out the classifieds -- the last 7 boats are BU's. What's the deal. Some are basically brand new... Am I missing something?
