Should i just upgrade to 2008 or not

[coldhammer]

So i like my 2006 except for two things.

the ride sucks. The interior creaking and rattling is driving me insane. I'm debating whether i should update to the 08 or if i can fix these issues.

Im not sure what the differences are in the suspension from an 06 to an 08 but the 08 definitely has a much smoother ride. Can updates be made to the 06 to achieve the same results?

Personally i like the interior look of the 06 better than the 08. but the interior noise in the 08 is practically non existent. Has anyone been able to address the noise issues either with dynamat or some other method? I am also a bit confused as to the origin of some of the noises. Some of the posts i have read seem to point to creaking being a result of the actually weld seams in various panels.

any input is appreciated.
