Mastercraft X-15

I am thinking about trading in the 2002 MC X-10 for a new X-15. There don't seem to be a ton of people out there with X-15s. What are the reviews from people who have them.

Also what are the major differences between an 02 X-10 and an 07 X-15?

Pics of X-15s with different color combos would be awesome too.

Thanks!
