Benny Katz usually has a few on his lot diagonally across from Playero or can get you one.
I know a person selling a nice Quad for sale, its a Yamaha 350 Warrior, I believe its a 2002. There's also a Honda dealer up the road at the next right after the tradewinds sign and entrance. If you want his contact let my know.
As a matter of interest, what would a quad like the Yamaha you mentioned go for?
