Audi A6 offers excellent driving comfort and its design has received various awards. AutoUncle offers an impressive selection of 1,828 cars in the UK compiled from different dealership websites and online marketplaces.
A used Audi A6 costs between £5,495 for the cheapest variant and £55,088 for the latest and most well-equipped model on AutoUncle.
The used car price for a Audi A6 can differ widely and depends on five primary factors: manufacturing year, engine capacity and performance, the car's fuel economy, how far the car has already travelled along with trim level.
For example, a newer model with fewer miles recorded, or a more luxurious variant with a powerful engine, typically commands a higher price than a car from an older model year, with higher mileage and no optional extras.
The most popular equipment variants for the Audi A6 are:
When looking for the best car deal for a used Audi A6, it is important that you only compare with the sale prices of cars with a similar engine and equipment variant. If not, you may make a wrong conclusion on which car to acquire.
The most popular fuel type for the Audi A6 is diesel.
Available fuel options:
Consider your driving patterns carefully when selecting a fuel type. How many miles do you typically drive each week? Are your drives mostly short trips, or do you tend to embark on longer routes?
Electric cars, plug-in hybrids and petrol are great for short distances. For long daily driving, electric cars are a strong choice if you can charge. For longer daily commutes, a modern electric car is often suitable - especially if you can charge at home or at work. For very long daily driving without charging options, a diesel car can still be relevant. It’s worth noting that diesel engines with high emissions are banned from entering cities in certain countries.
The Audi A6 comes in various body types, sedan being the most popular. Their four-door design means that saloons and sedans have long been popular with families. The distinct boot compartment ensures that luggage and other items are securely stored, away from the passenger cabin.
Though the Audi A6 is among the best selling cars in its segment it has some competitors.
