just got '06
I did a lot of research on my recent purchase of the '06 EXL RES.
Some I found were missing a lot of things, key remotes, floor mats, cargo nets, headphones for kids, the lazy susan in the floor, etc. If you are missing items make sure the price offsets it. You can get similar headphones, those are rarely left in the vehicle, FYI.
Our '06 the DVD sound comes and goes, which is actually a TSB for the wire connecting the DVD to the stereo. I have not fooled with that yet but the kids were complaining on our first big trip.
Brake rotors in front tend to warp, rear shocks tend to leak and need replacing. The rear motor mounts on these is VERY expensive to fix and mine was bad when I got it under warrenty at 54k, but would have been $900 at the stealer. Search on this for info, but if it vibrates the wheel and makes noise pulling away under power you might want to have it looked it before buying.
There has been powersteering issues with the assist coming and going at low speeds, apparently tied to a screen in the reservoir or the design, the new ones have a white dot on the lid.
People have also seemed to have issues with the door rollers wearing out in short order like 40k or so.
Good that you had the service done on the belt already.
That's about it for me. Also you might want to screen off the lower condenser / radiator as people have had rocks bust the condenser which is $$$.
I like the handling of the vehicle and the way it gets reasonable fuel mileage (I'm getting 24-25 highway), but there are issues - more than I expected even with the research I did.
