So.... in short, you need in addition to how your side x side comes from the factory:

Front and rear blinkers
A horn
A mirror that lets the driver see behind them
A light to illuminate the licence plate
A windshield or eye protection
A motorcycle endorsement
Insurance

DID I MISS ANYTHING?

300 bucks?

WOW!!!

What is a ballpark figure on what you need for it?

In my opinion there are pros and cons to both. The rhino is the machine off choice if you plan on adding a rear seat. Yes it can be done on a rzr but it does not seem safe and there is very little room for those in the back. The seating in each is very different and would come down to which "feel" you like best. The rhino does lack power compaired to the rzr but does have enough power to do and go anywhere you want to. The rzr can not be locked into 4WD. For a polaris it is actually called AWD system and you are correct in that it only kicks in and out as needed. However you do not notice that it changes back and forth while on the trail. It "seems" like it is in 4WD like you would want or need it to. It will always freewheel going downhill the way the engine braking works. You must push on the gas to engage the engine brake. The engine brake setup is far better on the rhino in my opinion. It just does not seem natural to push on the gas to slow down.

Bottom line it all depends on what you like and plan on using it for.

Hope this helps some. I am sure others will chime in.

Looks nice but way to much $ for a gas can. IMO
