Are you looking for a used Audi S4?

Are you interested in buying a used large sized family car? Then the Audi S4 is an excellent choice. AutoUncle has 93 used Audi S4s for sale in the UK sourced from various dealership websites and online marketplaces.

How much is a pre-owned Audi S4 worth?

A used Audi S4 costs between £8,990 for the cheapest variant and £39,990 for the latest and most well-equipped model on AutoUncle.

The cost of a pre-owned Audi S4 is determined by several factors. Key contributing elements include the year, engine size and performance, fuel efficiency, mileage along with the vehicle's equipment variant.

For example, a younger car with fewer miles on the odometer typically costs more. Likewise, models at the premium end with luxurious features or potent engines tend to come with a more substantial price tag than a used model with many kilometres on the odometer and in a simple equipment variant.

Which equipment options does Audi S4 have?

The Audi S4 presents a wide variety of trim configurations, tailored to suit various driver predilections and needs. The most popular ones are:

When evaluating the costs of pre-owned Audi S4, it is crucial only comparing the offers of cars with a similar equipment variant and engine size. If you don't, you might reach a wrong decision on which car to purchase.

Can I get the Audi S4 with different fuel types?

The leading fuel choice for the Audi S4 is petrol.

Types of fuel:

  • Audi S4 petrol: 66 cars currently available with an average price of £18,768
  • Audi S4 diesel: 27 cars currently available with an average price of £32,819

We advocate for a careful review of your driving habits before you commit to a fuel type. Do you find yourself driving more in urban settings or on open highways and expressways? How much distance do you travel in an average week?

Electric, plug-in hybrid and petrol work well for short trips. If you drive long distances on a daily basis, an electric car is good - especially if you can charge at home or at work. 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. Keep in mind that diesel engines with high emissions have been banned from entering cities in a range of countries.

In which body types are the Audi S4 available?

The Audi S4 is available in both stationcar and sedan body styles, with the stationcar being the more popular choice. Estate cars, also known as station wagons, are highly sought-after in today's market. They meld superior driving dynamics with abundant space, making them a favourite choice among active families, alongside SUVs and MPVs.
