Personally I think its a fair price. Yes there are cheaper examples out there, as there always is (as with any make/model), but the question is how much is it worth to you? If you want to buy a 11K-12K example, then discount this one immediately and save your energy.
Personally I always look for the best well maintained example I can find and try to buy privately from someone who has actually looked after their car, oppose to car dealers who are number crunching on business turnover (nothing wrong with that, just not my preference) and this at times can be a little more expensive believe it or not.
