Dont look at the price first, that can always be negotiated, just go look at the car, if you like it, then talk about the price.
The price can always be knocked down slightly, but 14k is pretty cheap for such a new car. As mentioned many times on the forum, kilometers don't matter, look at the overall condition of the car. It might be a 97 s2, but if its trashed, its gonna be crap. Just take it for a test drive, if its in good nick, 14 isn't all that bad, but ask for a discount anyway.
