Not worth it? Come on it only has 105k miles on it. And they were probably all highway miles.....
Plus the backseat is in excellent condition! (Maybe from the fact that besides a midget, no one would want to fit back there?)
So if you can get past the fact that he won't ship it (too expensive to ship?), don't you dare ask for any more photos (pictures put unnecessary stress on the car I guess), It was well-maintained running-wise (wtf does that mean?) and the wonderfully low price of only $25,000 (that's like what 3 or 4 s30's?) then I say go for it.
