I own a Rhino, Prowler, and Ranger XP. All are '08 700 EFI. None of them are junk. The Rhino is the slowest, roughest riding, and is the hardest to get in and out of. This machine will require extensive mods to equal either of my other two machines. The Prowler has decent power and a fairly roomy interior. I've heard that the Rhino is more durable, but the Prowler beats it in every other catagory.
Now for my favorite. The Ranger XP, it's not really fair to compare this silky smooth running twin to the rough running singles. The ride is equally impressive. Between the smooth engine and the smooth ride I really don't enjoy driving my Rhino or Prowler anymore. It's slightly larger dimensions are not a problem. This machine is WAY better than the rest. I paid less for my XP than either of the others. Also it's exclusive "on-the-fly" shift into all wheel drive can mean the difference between forging through a difficult area or stopping to shift into 4WD and ending up stuck. And finally the solid dash mounted shift works perfectly EVERY time, unlike the flimsy little "between the buckets" shifters.
I test drove the Teryx. It rates close to the Prowler but no EFI available.
