I have a 2003 x30. I LOVE IT. Its not as uncommon as you might think to hear someone pushed it too far in the season and wound up with a frozen block. That being said he probably learned is lesson. Just get it properly inspected. As far as the interior goes??? Yep t was thin in those years. MC has since improved. As we speak Jim at Viper customs is redoing my entire interior.
Depending on the price... It's one heck of a boat!
