I am thinking about buying a quad, I have rode them lots of time, but don't know alot about buying them. I found alot in my price range (~$2k-$2.5k) with 250cc engines, are those pretty slow, or decently fast? I only need to go like 30-50ish, but I want power if I go to the dunes and such. I am mainly going to be doing trail riding and such, maybe take it down to the dunes once or twice a year. Should I keep searching and try to find something with a bigger engine, or is 250cc's enough?? Thanks in advance. EDIT - I did find one with a 350cc... http://adcache.atvtraderonline.com/5/9/4/87903994.htm Is that a good price? Good Quad?
