I am in the market for my first quad. I want to buy used and price isn't a concern, I want to know what is the best value as far as how much you save over buying brand new. I am very accomplished as a rider because I have been fortunate enough to have alot of mean machines at my disposal pretty much as I please, and am finally financially able to buy my own!!! (Whooo-hooo!!) Any opinion would be greatly appreciated.Oh yeah, I want a four stroke.
