If it does not have and independent rear, then it is not a Rincon. They have all had it since it was introduced in 03. I don't know who quoted you that price but it is not a Rincon. An 06 is going to be at least $6500. The only machines offered with GPS but not IRS is the Rubicon, Foreman, and Rancher AT. Also camo was not available on Hondas until 06 and only on the Rincon. For 07 it is available on some others.
I would say the price they gave you is for a Foreman or Rancher AT.

 

You must have gotten a price on the Rubicon. They don't have the IRS. As Foremandan stated all Rincons have had IRS since the first ones in 03.

 

Hey Rinman:

My mistake. It was an 05 Kawasaki dual cylinder 650 quad. The model name escapes me at the moment. It was dark green with a solid rear and GPS. Automatic (with belt drive), on demand diff locks, and EFI. It seems to be big and strong enough for me (I'm six-three). That?s it for now. When I find the business card the dealer gave me with the info, I shall post it. Thanks again. Chris
