It looks like all of the current incentives are going to the dealer. As far as the pricing mentioned above on a 2011 Limited 4x4 with V8, 730N, and the 20" Rims, as well as the "credit" for the single pane sunroof, you're looking about $36,400 through USAA. As I had mentioned in another post, you do not need to be active or past military to join USAA and use their car buying service. Anyone can join via their website and use this service.
For comparison, I bought my 2011 Limited 4x4 V6 with the 730N and Trailer Package with an MSRP of $41,150 for $33,339 the weekend before last using USAA as a starting point. Two dealers offered the same price through the USAA service, and the 3rd USAA dealer offered to beat them both by $500. Most dealers in my area were offering $5-6k off MSRP for anyone, closer to $7k on some of the V8's.
According to TrueCar.com, my purchase would have been the cheapest '11 with these options sold in the country. Whether I fully believe TrueCar.com is debatable...nonetheless, I think I got a pretty fair deal.
On a sidenote, the dealer I purchased from based in Minneapolis had to go about 300 miles away to even track down a 2011 with the V6, as the only thing left in the Minneapolis/St. Paul area seems to be Hemi Limiteds, a few Overlands, and a bunch of Laredos with the 70th Anniversary package. Kind of suprising considering there are about 15 dealerships within 50 miles of Minneapolis.
