I've heard the liners fit very well. Unfortunately, I got a set of the mats a while back for my 05 and the rears are fine but the fronts really don't fit well at all. I assume they would fit the KK but the description said 02-07 also. The hook hole is on the wrong side. Think it was AutoAnything. I guess I should have gotten the liners but don't really have a need for that level of coverage.
for the most part I've enjoyed my Weathertech floor liners for my '07...the one piece rear liner tends to bend inward on the outer edge of each passenger side, but other than that, they provide great protection and are super easy to clean.
