It is all relative now.
I would not buy a car based on reliability; no automaker is producing really crappy cars that are going to break down all the time.
I was speaking from my personal experience with Toyota, (granted I am bitter of there treatment of my mother) I will NEVER own another car with Toyota on it.
If I was going to wheel something new I would buy a Jeep Rubicon (I did as a mater of fact).
I wheel all the time with an 03 Xterra and it does OK, can't go the places I can on trails but it was way better in sand.
They are marketing this as an off road capable vehicle like the original was.
That market is the Hummer H2 and H3, the Nissan Xterra, the Powerwagon, and the Jeep Wrangler.
The Mopar products are the kings of the hill off road. The H2 and H3 and 05 and Newer Xterra is really what this is aimed at since it is also an IFS Car.
I bet 2 years after Toyota puts this thing on the market, someone comes out with a solid axle swap for it .
