Drive train is aged 3 years, probably needs rebuild. For $10k it should be nice and tight. I would be weary of the deal. Bring a refrigerator magnet with you and see if sticks everywhere, if not, it got lots o' filler.....
Of course, looks for custom touches and mods, he may feel it's worth it if there's a bunch of work in it. Hard to say without pics, additional details.
