Why buy a used Audi A6 Avant with Exchange and Mart?

You might not expect one of the most aerodynamic combustion models Audi has ever made to be a big A6 Avant estate - but perhaps you should. Slippery bodywork has always been a calling card of this model line. The very first C4-series version of 1994 was a re-badged version of the most slippery big car of the '80s and '90s, the Audi 100. And the first bespoke design with an A6 badge, the C5-series model of 1997, set another new standard for how slippery a big estate could be. It's successors, the C6 design of 2004, the C7 model of 2011 and this current car's predecessor, the C8 design of 2018, continued the trend of form over function. Customers could fit much more in a rival Mercedes E-Class Estate, but the A6 Avant always vastly out-sold that model in our market, whilst also trumping the other big segment player, BMW's 5 Series Touring. This C9-generation model, announced in early 2025, was originally supposed to switch to 'A7' badging so as not to cause confusion with the all-electric A6 e-tron launched in 2024. But a last-minute change of policy by Audi saw this combustion model keep the 'A6' moniker. It's still offered in diesel form as well as in petrol guise - it'll actually be one of the last diesel models Audi will ever launch. And there's a saloon version too. But here our focus is on the Avant.

About the Audi A6 Avant

This, even BMW and Mercedes would reluctantly have to admit, is a beautiful piece of engineering. It always has been. The A6 Avant was, after all, the first cars in its class to offer things like bonded-in flush glazing, a galvanised bodyshell, V6 TDI power, four wheel drive and advanced twin-clutch automatic gearboxes. And in this improved smart-suited sixth generation C9-series guise, the cleverness continues, an extra dose of visual charisma blended with high technology and premium quality unsurpassed in this sector. This car's drawbacks, such as they are, don't appear to bother many potential buyers. No it's still not the most spacious large executive estate in its class - but these days, it's large enough for that not to matter. Yes, the extras can be expensive, but then that's the case with any premium executive car. And it's true that the handling still isn't especially aimed at driving enthusiasts, though you can go a long way towards sharpening it by ticking the right options boxes. This then, is a very complete product, perhaps a fitting sign-off for the combustion A6 Avant model line, if that's what this C9-era design is. A thorough case, if ever there was one, of vorsprung durch technic.
