Thanks for the replies.

I like the Honda, Polaris and Arctic Cat quads. My daughter likes the Polaris Sportsman 90 simply because it's just a smaller version of mine and we have a local dealer. The Honda dealer isn't too far away and I wouldn't mind driving the distance if the machine is that much better. I do like the Honda because of the gears and I know that it will help keep their speeds down when going down hills, however it doesn't have reverse like the Polaris does. I also like the fact that the Honda is probably more water proof than the Polaris. I am not sure what it would take to make the Polaris more water proof. What kind of accessories are available with the Honda? Can you add racks?
If the choice comes down between the Honda and Polaris is there that much of a difference that the Honda would be a better choice?
