any tips for finding certain used quads?

[450raider]

well by the summer im gonna try to save enough money for a ute, i was originally wanting another sport quad but the ones i got now are perfect for me and finding another ute may be cheaper, so now im trying to find a used wolverine 350 (the original ones) i thought they were perfect for fast paced 4x4ing, (anyone have other suggestions) i did years ago briefly own an 04 for like a month and liked it but traded it off to get my brother somethin, and i didnt really learn much about em like what changes yam made in what years? if i wanted one identical to the 04 how far back could i go? about how much would a well cared for one be worth? wheres good places to look?

thanks for any tips / info
