I checked it right off the MBUSA site so I believe this is accurate, you can double-check if you want to. Yes someone with an existing Starmark warranty I believe can transfer it or cash it out, but again check the website:

Go to the above page, and towards the bottom, click on "report instructions", it lists the "Starmark stoppers", can't link to that page directly.
