Paid £5500 for my 2.0 (I dont think there is any price diffrence at all between the 1.8T and 2.0) over a year ago now on 62K (I think, something like that anyway). Does that make you feel an better? The price will vary greatly depending on the car condition, year of registration and the milage its sitting on.
Stick up your year and milage its on and id tell you what id pay for her.
