I paid a £500 deposit on an Audi A6 2.7 diesel Avant with 57,000 miles on the clock. I asked if the car could be taken to an Audi specialist nearby for a pre-purchase check, but they would not allow it for insurance reasons. However, they assured me that it had "been through their workshop" and had a new MoT.

I picked the car up last week and traded my old A6. I told them I will have it checked. I took it to a nearby garage for an inspection and they have identified over £2000 worth of work that needs doing. I would be very grateful for your advice
