I'm not going to go back through and read the entirety of the posts, but I believe I mentioned before about getting the BBB involved. If they won't, or if you're out of options then I'd honestly just sell the boat and move on. If you're unsatisfied with the boat now, then continuing to own the boat for additional years and years on top of that isn't going to make you like it any better. The situation definitely sucks and if what you say is true, it would be infuriating that Grady doesn't want to help you out at all. That being said, it's pretty much a brand new boat and I believe most of the issues are cosmetic only, so you should hopefully at least be able to break even on it?
