Should you buy one?

Yes, with a couple of large provisos. The A6 is a very accomplished all-rounder which over the years has established itself as a roomy, refined and economical saloon that rewards drivers who cover huge mileages.

Opt for the entry-level 40 TDI (a high-power 2.0-litre diesel in old money) and fuel and servicing bills will be low for both private buyers and company car drivers. Strong residuals mean finance packages are good value, too.

However. The BMW 5 Series is a much sharper drive and the Mercedes-Benz E-Class has a far more modern interior and infotainment setup.

If you value refinement above all else and you can find a good deal (say, circa £350-£400 per month) then the A6 is worthy of your payment. Ultimately it’s beginning to feel its age and most people would be better off with something from BMW or Mercedes.

What we like

The A6 does classy and understated like few others. The interior is very well made and thought out, plus there are two petrols, two diesels and a plug-in hybrid to choose from. And apart from the base petrol, all make a good choice.

What we don’t like

As with many Audi models, it’s all too easy to delve deeply into the options list and spend a load of money. The warranty is stingy, the looks are a bit staid and the ride is too unforgiving for a luxury car.
