2012-reg Diesel, Owner for less than a year

The car had a problem which was not picked up in the pre-delivery inspection which meant it was off the road for a few weeks just after it was delivered. since the fault was rectified, there have been no further problems. The car is economical for the size of engine. the servicing costs are covered by a one off payment of ł230 which gives you 3 years servicing.

Couple of minor problems in year 1 fixed promptly under warranty and without question. alternate vehicle of same make/model provided by dealer whilst worked carried out. Fuel consuption is average for the vehicles age/engine. 3yr servicing package covered all requirements for the first 5 years.

The 3 litre Audi A8 TDi Quattro is simply the best car ever - I think the only better car would be a Bentley ( built in same factory ) or Rolls Royce but for the time being they remain out of my reach. Mercedez Benz S Class or BMW 7 Series are no match.

Perfect, it has never given me any problems. It's a bit thirsty, but it's a 6 litre car, so what do you expect.

No faults to date. Expect servicing to be expensive but good on fuel.
