Re: Rushing to get the 2014 Grand Cherokee
The WK had a moderate refresh in 2008, a lot of the electronics etc changed.
The changes that were coming in the '14 had been known for quite a while. Some things were just not available when the WK2 first came out, but have since become the standard across many Chrysler lines; it would be insane to arbitrarily hold that back and end up with a non-competitive vehicle in later years.. that wouldn't help your resale value either.
Some people here prefer the '12/'13 for various reasons, so it is not entirely one-way.
2007 WK Limited 5.7L
2014 WK2 Overland 5.7L
And a few past Durangos
