Just out of interest, how much is it for sale for?
Also, milage that low isnt always a good thing on a 4 year old car. maybe lots of short stop-start journeys? this can mean a worn clutch and even worn turbo bearings due to the lack of time taken to warm up the car and allow it to cool down properly.
12k miles is 3k a year or just 57 miles a week on average. (a turbo blew on my first mk5 at just 13k miles due to being used for short journeys for 3 years of its life, we get a lot in the workshop with problems at very low milage but a few years old.
