Thanks for the fast replies. This doesn't need to be a fast purchase so I'll take a look at the dealership when I'm back stateside in a week or two - ironically my corporate internet blocks their website so I haven't looked too closely beyond the CraigsList ad (which I forgot in the original post:
https://phoenix.craigslist.org/evl/snd/4948283299.html). Looks like the warranty is factory only, so if I don't see an issue on a test drive it is my issue.
