Have wondered if you had decided about the '03 yet. We have an '06 and like Alpines. However, I would not be opposed to buying an '03 at all. If fact, sometimes I think that is what we should have done (don't think we need all the fancy electronics). Many people think one is just buying someone else's problems when they buy used; however, we have always had good luck with used--whether it be cars, trucks, motor homes, etc.
As for calls from WRV,when we have had issues, the repair service says WRV calls back as soon as most manufacturers and sooner than some. I have called personally several times and have had good response. I realize this is dealing with a new one, but just thought I'd share this experience.
Let us know what you decide.
