I've had my 99' wolverine for over 2 years now, I love mine, I made several upgrades to mine, the machine is very affordable to own, I am 17 and am paying for it by myself and upgrading as well, I would recommend the pro-design filter conversion kit with the uni foam filter, this will assure the air filter seals inside the airbox. This is the only thing other than skid plates that I would have to make. I have installed a procircuit pipe, prodesign filter system, full prm skids, shock wears, warn winch, renthal bars, and a moose plow for the winter.
I love mine.
