Bought a used 2005 the other week and love it so far. Very solid. I have noticed a squeaking, rattling like noise that seems like its coming from the back seat or somewhere in the cargo area. I only notice it when on rough road or significant bumps. Went down to a friends farm last weekend and it was pretty significant on a rough dirt road. Ive poked around in the back a little but can't find anything that might be causing it. Perhaps it's not coming from inside...maybe tire mount underneath? I had an old blazer that had the spare tire mounted on the side in the cargo area and had a similar type squeaking sound. Anyone experience something similar.
