First, despite what some guy said, there IS a V8 version of 4Runner.
In my 20+ years as a Mechanical Breakdown Inspector working for all major extended warranty companies including chrysler contract, I still cannot understand who would take chances with a jeep...
I am having a hard time wondering why people think the WK Grand Cherokee is a Uni-body? This was the only GC that was a true body on frame design.
I am in this same quandary and thinking the WK with the CRD and QDII. It honestly just blows the ATRAC system clean out of the water. Both have lots of mods available and honestly, if you take care of anything, it will last you forever... I had an Land Rover LR3 that never left me stranded.
