How long did this air filter mod take you?www.sbsparts.com

Those look nice, and at a great price.  Do you sell rear windows for the Ranger midsize like the one in this tutorial.this tutorial

Might want to consider some A-arm guards while you're at it.www.sbsparts.com

I would also recommend the extended cage for safety reasons, if you roll that thing it's bad news for your passengers.

Well, this is an easy one and not just because I'm a UTV fan, but from a durability standpoint you should definitely spend the extra cash and get the Teryx.  I owned a business where we used gas golf carts for six hours a night and they broke every week.  Even the new models just are not built well.  UTVs use brakes, engines, transmissions and other major systems borrowed from cars, trucks, ATVs and even snowmobiles. Golf carts use lawnmower engines, mechanical brakes and cheap plastic in places where only metal is appropriate. If your wife is concerned about safety, get a good set of aftermarket seats and harnesses.  The cages are built to keep passengers safe in the case of a slow roll over,  just make sure your son gets a good feel for the Teryx before you let him loose.  In another five years you won't see a golf cart used anywhere but a golf course. Happy riding! Below is a good review of the Teryx 4, with your family you should consider the 4 seater, they come in very handy!

Heads up, the new Viking is out.  It's got a 686cc motor, a reliable power plant but you may have trouble finding good mods for the first six months.  Good news is you should be able to get a screaming deal on a 2013 Rhino while they're still in showrooms.  Check out good review article hereSBS Parts Blog
