I looked at the L3, a Mercedes M series, the Jeep GC and was driving an Explorer at the time. From what I understand, Ford is going to stop making the Expedition so that could be a problem. The MB M drove like a car and I'm used to an SUV. I saw too many articles about troubles with the L3 and the closest dealership is 60+ miles away.
I ended up with the Jeep GC with the Hemi and I really enjoy driving it. It has all the bells and whistles and I think 2007s have even more than the 2006s.
However, I have a neighbor with the Toyota and he LOVES it

I have a Wrangler and that's my playtoy, but if I didn't have it, the Toyota would be a fun 2nd car.
The Hummers I've never liked for some reason.
