Here's a project for the woodworker: replace the cheap plywood sliding cabinet doors with raised panel inset doors. This improvement makes an amazing difference in the quality of the interior. Of course if you have to pay someone to do the work, this could get pricey.
I also recently replaced my overhead hatches with the stainless "Traditional" line from Hood yacht systems. This also made a big difference in the exterior appearance since I already replace the portlights with the stainless.
I think I'm passed the "re-sale threashold".......I better keep her.....
