I wish my dealer would sell me a Rubicon for $6300. He won't budge off of MSRP + setup + freight, sales tax.

The expedition for 3600 appears to be a fair price. The Rubicon & Traxter are in a different class than the expedition. If you think the Rubicon is expensive have priced out the Traxter?

From the three you have listed the Rubicon is the best, followed by the Traxter.

You have to decide do you want new or used? Both new ATV will come with a warrenty & the used Polaris will not, unless it has the extended warrenty but you didn't mention that.
