Axis A22 interior, quality? longevity?

I have a good friend who is considering the Axis A22 for his purchase this winter for 2013.... he is a concerned about the longevity of the vinyl and how it will last. He covers his boat when not in use, but definitely uses them. Usually 150+ hours a season.... Apparently Malibu is using a lesser quality vinyl product than they use on the Wakesetter series.

Does anyone here who currently owns an Axis have any feedback on how the vinyl is holding up. For people who trade there boat in every year please do not reply, looking for someone who has a 3-4 year old boat and what there experiences are with the vinyl quality against tearing, fading, etc.... and how many hours are on your boat.
