"Owners praise the A6 Mk3 for its impressive performance, comfort, and reliability. Value for money is considered good, though efficiency and ride quality in sport mode receive some criticism. Some practical aspects, like difficult engine maintenance, are noted as drawbacks. Overall, the A6 Mk3 is a strong performer with a few practical compromises."

Twin-turbo V10
Wish it was easier to work on it, it's engine-out for most major jobs like new turbos and oil seal repairs.
I'd say 8 out of 10, let down by the ride quality in sport mode being too stiff to ever use, and the fact it needs engine out for most major jobs. It's actually not bad on fuel for what it is, doing around 340 miles to a tank, just over 20 mpg over a mix of motorways and b roads.
