Well, you don't need to worry about a CVT since you don't have one, but keep an eye out for typical Chrysler suspension problems. I think Moog is still about as good as you can get on that front. Manual transmission could probably still use a little preventative maintenance, though of course it won't be as touchy as the alternative that I'm known for liking so much.
Spark plugs could use a double-check. Some Patriots like mine can run on double-platinums if they're gapped right, so you don't need to change them quite so often. Other owners swear their ride won't run good on anything but the NGK coppers that the factory puts in.
Maybe give the brakes a quick look just to be safe. Mine is probably just an odd case, but the rear brakes started scraping what was left of the pad against the rotor at 32k-ish miles, and the front brakes needed replaced not long after. I've had to replace pads and rotors a few times since, even calipers a couple times. But others say that their original brakes from the factory lasted 100k+ miles. I'm closing in on 140k.
And of course, you probably know about the tire wear bars inside the tread. When the time comes for new rubber, assuming you're planning on leaving the pavement, I've got Cooper AT3's in 215/65/17(stock size for my FD1 because tire/wheel group, and all FD2's) and I love them. Didn't even have to recalibrate the computers. Not too heavy, good traction for what I do, very well-balanced tire. But if you don't mind extra weight, don't mind adjusting the computers or just having the speedometer and odometer showing the wrong numbers, and just want the beefiest possible tire in the biggest possible stock size, then you'll probably want BFGoodrich KO2's in 225/65/17, which is the biggest known size that any tire can fit without rubbing.
