I have an 05 Hemi quad cab 4x4. It's needed the following work in 108,000 miles:

Under warranty:
Water pump
Driver's seat upper cushion replaced
Power steering rack/pump/lines (they replaced all of it).

Out of warranty:
Pinion seal ($20, did it myself)
1 EGR valve ($40?)
2 sets of power window switches ($30 apiece)
1 set of brakes ($150)
1 set of tires ($700)
1 driver's seat (may have been due to the warranty repair, I think it was reassembled incorrectly and then broke). ($100 from a junkyard, reused my old cover).
2 sets of plugs ($50)

...that's about it. It has spent it's entire life in the northern midwest, and the rust has really taken off in the last year or so. Holes above the wheelwell, some in the rocker panel, some on the inner door seams, and one hole in the quarter panel area down by the tailpipe. You clearly won't have the rust issues, though!
