Are you looking for the popular Audi RS6 used?

Are you considering getting a used executive car? The Audi RS6 is a solid choice. At AutoUncle, we have assembled a collection of 132 used Audi RS6 cars, each one sourced from an online marketplace or dealership website.

What is the price range for a used Audi RS6?

The oldest and cheapest Audi RS6 here on AutoUncle is available for £27,990, and a more recent model with a higher equipment level costs around £109,995.

The German car is valued at different prices based on mainly five factors: year, engine capacity and performance, fuel consumption of the car, how many miles it has travelled along with the vehicle's equipment variant.

For instance, a car that is newer and has fewer miles on the clock will typically command a higher price. In the same vein, models at the higher end, replete with luxurious features or more robust engines, generally come with a more substantial price tag than, for example, an older model with more kilometres driven or with a lower equipment level.

Does the Audi RS6 offer multiple trim lines?

When evaluating the costs of pre-owned Audi RS6, it is essential that you only compare with the prices of cars with the same equipment variant and engine size. If not, you could make a wrong conclusion on which car to purchase.

Which fuel variants are most in demand for the Audi RS6?

The principal fuel kind for an Audi RS6 is petrol.

Audi RS6 fuel types compared:

  • Audi RS6 petrol: 110 cars currently available with an average price of £61,562
  • Audi RS6 hybrid: 22 cars currently available with an average price of £93,144

There are a few questions you should ask yourself when deciding on a fuel type. Do you generally drive in city conditions or on open highways and motorways? What is your average weekly mileage count?

If your trips are mostly short, electric, plug-in hybrid or petrol may make the most sense. For daily long-distance driving, the electric car is often ideal - especially with a charger at home or at work. 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. Diesel cars can still make sense if you drive very far and don't have access to charging. Be aware that in a number of countries, cities have implemented bans on diesel engines with high emissions.

What kind of car is the Audi RS6?

With the stationcar being the more popular choice, the Audi RS6 is offered in both stationcar and sedan body styles in the UK. Estates, also known as station wagons, are popular in the current market because they offer the combination of excellent driving capabilities and the advantage of lots of space. Station wagons, SUVs and MPVs tend to be popular with active families.
