Re: Considering used Crossfire - what to look out for?
With that many miles, it probably just got new tires - if not, take a close look: PLAN ON NEW TIRES REAL SOON and figure that into what you will pay.
I think they are pretty solid cars overall - all the typical thoughts apply: DRIVE it, LISTEN to it and IF you can, see if you can inspect the area it's been sitting in - look for the usual leaks.
Other than the fact that you don't get 60,000 miles on a set of tires, I can't think of much I'd look for other than the usual used car stuff.
(But I KNOW I am missing some stuff, and others here will chime in.)
