Thinking about buying a 2004 Polaris 800 Classic with about 2800 miles on it. Anybody got an idea of what it's worth ? The guy is asking $4000 or offer and it is pretty clean. I assume the 800 has the same VES and crank issues as the XC's and I was really looking for a 600 or 700 Classic but this came along and I'm wondering if it is a fair deal or not
