Faults:

Clutch, plus general wear and tear.

Climate control sometimes has a mind of its own.

General Comments:

The A6 is expensive to buy and run, but well worth it if you get a good one.

Buy nothing less than a car with complete history. Then you can relax despite having higher mileage, these cars are good for it. Follow the service schedule to avoid expensive disasters.

The 2.0 diesel moves quick and you can still get 50 mpg + more taking it slow. The car is amazing to drive. Would suit an automatic box more, but the manual is OK to use.

Interior is where this car shines. Black leather, very supportive seats. Electric everything. Every journey is a pleasure.

Gorgeous to look at in black. For 10 years old, it looks as good as new and I love it.
