My 99 GA SE (more or less the same thing as a 02) has had little problems, running at I think 120K+ now i've only had to change the tires once at like 75K (BFGoodrich Touring T/As), had to replace the front passenger wheel bearing, had to replace the ignition lock cylinder (common security problem in 99-01), and regular oil and filter changes. And spark plugs just because I felt like it

.
Body wise it couldn't live in a tougher environment in Iowa, the summer time is hot and humid, the winter time is freezing and dry. Its only got a couple small rust bubbles that I'll need to have fixed, maybe. The paint has been pretty well beat up on the bumper, following to close to semi's kicking up sand in the winter time. I've got to replace the windsheild as it developed a huge crack in it some how, no impact that I can find.
If I ever trade it in, it'll be for another grand am thats for sure, besides preventative maintenance (oil, filters) I don't think I've yet spent over $1k in it. Not to bad I don't think.
