I just drove one at my dealer last night. I wasn't real impressed. The acceleration from stopped and from 50MPH was only slightly better than my 06 (45,000 mi, stock intake and exhaust). I was considering a trade-in, but after driving it there was no compelling reason to do so. I personally love V8's, but there was absolutely no WOW factor with that engine in either the power or the sound. I had to turn the AC off and open a window before I could hear the engine. I know most buyers don't want a loud engine, but if I have a V8 I at least want it to sound that way. At least a little growl.
The one I drove didn't have many options besides the sunroof, side steps, and rear view camera (displayed through the rear view mirror) and the sticker was 41,750. I would at least want the off-road package.
Anyway, that's just my opinion and some of you will probably disagree.
