We boated with a family who bought one new in '03. Pretty much everyone in our boating group tried to talk him out of buying a new boat in it's first production year. He bought it anyway and to sea rays credit, the boat had very few wrinkles that had to be ironed out. I do recall some problem w the qsm11s early on but it was easily rectified. Maybe some of the qsm11 owners know the details. Nevertheless, they sold it last year and to my knowledge, the boat had a clean history mechanically and structurally. As far as best bang for the buck or sweetspot, cant help you there, but I wouldn't hesitate on any one of these 50da models. Good luck.
This wouldn't have happened to be "A Family Affair" would it? All white hull with Blue Canvas? Low hours?
