I know it doesnt help much but here is a little story. I have a good friend that several years ago bought a very nice looking and well appointed yacht, a Californian. This model is like one small step down from the Navigator and was like 400k to 500k. He bought it brand new at a boat show in Seattle. The boat is made in Paris Ca a full 80 or 90 miles form any body of water big enough to float it in. It was like hull number 2 and had lots of problems in fact he was found of saying that they were so eager to get it to this boat show the he was sure there were still workers in the bilges bolting things together as it rode on the truck to the show. list of things went from not enough ventilation around the fridge so it kept burning out to motor mount on the engines that were only finger tight. And while he did place claim for the big things much of it he just fixed himself. WhenI asked him why he didnt take those things to the dealer her would reply " well no one care as much about my boat as I do"
I guess the moral, to paraphrase Roseanne Roseannadanna, is no matter how much you pay its always something
