Well the 06 was 54,100, and the 07 was 69,900. 06 had less than 30k on it, and the 07 had 48'ish.

Handling feels about the same to me, though I didn't drive the 06 for too long. I do find that with the same winter tires on, I find the 07's back end comes out a bit more on ice. Probably has to do with torque distribution, but it's hardly an issue unless you're powering through 90 degree corners. I find that the 07 is alot more comfortable (that door handle on the drivers door no longer jabs into my knee, making it difficult to change mirrors on the fly). And on the road it just feels smoother.
