I have a first year 2011 Kubota 400 ci EFI UTV. Great little machine. Steel dump bed. Will tow small trailers with ease Simple machine except for the fuel system. Caution: if the throttle body system needs to be repaired or replaced, you must buy the paired ECM to go with it. Last time I checked about $1,500 for the parts alone.
On another note, you can fulfill your budget requirements with a deal on a Polaris 570 Full Size 3 seater or a Can Am Defender 800 3 seater. Both are impressive machines with far more room, horsepower, and torque.
