Get it detailed, i.e make it look utterly mint - get decent pics up and it should sell.
I bought mine last year, very simailr car, 73k, grey, leather, 3.0, 53 reg etc for 8.5k. Last April! Bargain, it looked SO mint in the photos, and was when I went to look at it. You soon forget any mileage worries when a car is very very clean.
