Where exactly is the mileage stored on these A3's? Because i've just had a look through my service book and the car was serviced religiously every year for 6 years at an audi dealership and it was doing about 20k a year! Then for two years it went totally of the radar and the mileage doesn't seem to add up considering it had the same owner from 2004 until I bought it in august. So i'm just wondering if there is anyway to check the mileage?
