I'm gutted, not only to find it out, but knowing i was so stupid. I bought a 2001 a3 1.8t from an autotrader dealer with 105,000 miles. It didn't have the previous mot's or service history. I was a bit dubious, but as they were a dealer i stupidly trusted them. I went on the direct.gov mot history checker this evening. Check your vehicle's MOT status and history online : Directgov - Motoring (click on mot history check) it turns out that the feb 2011 mot showed the mileage as 145,000 !! So it could be anything upto 160,000 by now. has anyone had previous experience of this? lesson learnt. i will never ever hand over money unless i have a good amount of history with the car. i have retrieved this info from searching the net, think i'll phone him tomorrow.
