I'd go Wolvy 450 4x4 all the way.... or a Can Am Renegade 500 (if you can find one used for that cheap, not sure how much they go for around there).

 

id wouldnt go with a honda rancher unless you wanna put tires on it because the rear end is soo low you will tetertoder in the mudd hapens to my friend all the time

 

I can get you Supermach ATV-400 that is about $3500 depending how close you live to me. You can look at them on Supermach.com

 

You can find a 660 Grizzly in decent shape for great prices now and they have diff lock and hit 65 MPH easily. They will smoke a Wolverine 450,420 Rancher and most of the above ATVs mentioned so far in this thread.

Lots of money to be saved buying used. I would rather have a used 660 grizzly than a New 450 Grizzly any time if they are the same price.
