Are you looking for the popular Audi RS6 used?

Are you considering buying a pre-owned executive car? Then the Audi RS6 is a great option. On AutoUncle, you can find 202 used Audi RS6s for sale in the UK collected from various dealership websites and online marketplaces.

What is the used car price of the Audi RS6?

The cheapest Audi RS6 that is available here on AutoUncle costs £27,989, while the most expensive model is priced at £118,385.

There are five main parameters which have an impact on what a used Audi RS6 costs: what year the car is from, engine size and performance, fuel efficiency of the car, how many miles it has travelled along with equipment variant.

For example, a newer model with fewer miles recorded, or a more luxurious variant with a powerful engine, typically commands a higher price than, for example, an older car without special equipment and with many kilometres behind it.

While evaluating the cost of a pre-owned Audi RS6, it's crucial to examine vehicles sharing identical trim level. Otherwise, you might draw an inaccurate conclusion about which car to purchase.

Can I get the Audi RS6 with different fuel types?

For the Audi RS6 petrol stands as the only fuel type available. At present, we have two hundred and two cars at an average price of £67,552.

Keep your driving habits in mind when choosing which fuel type to purchase. How many miles do you drive in a normal week? Do you take many short trips, or do you tend to drive long distances?

For short journeys, electric cars, plug-in hybrids or petrol cars are obvious choices. If you have a daily commute over longer distances, a modern electric car can be a great choice - especially if you have access to charging at home or at work. In a few cases with long journeys and limited charging infrastructure, diesel can be a practical solution. Be aware that in a number of countries, cities have implemented bans on diesel engines with high emissions.
