Looking for a used Audi S4?

Are you considering buying a used large sized family car? Look no further than the Audi S4 - an excellent choice! At AutoUncle, we have assembled a collection of 69 used Audi S4 cars, each one sourced from an online marketplace or dealership website.

How much is a pre-owned Audi S4 worth?

A used Audi S4 costs between £7,990 for the cheapest variant and £35,989 for the most expensive model.

The price for the German car can vary a lot and depends on five main factors: the year, engine capacity and power, fuel economy, how far the car has travelled along with the level of equipment in the car.

For instance, a more recent model with limited mileage, or a premium variant featuring a powerful engine, typically commands a higher price than, for example, an older model with more kilometres driven or with a lower equipment level.

What equipment variants is the Audi S4 available in?

When assessing the price of a used Audi S4, it's essential to compare vehicles with identical engines and equipment. If you don't, you might draw an inaccurate conclusion about which car to acquire.

What are the fuel options for the Audi S4?

Petrol is the foremost fuel option for the Audi S4.

Types of fuel for Audi S4:

  • Audi S4 petrol: 53 cars currently available with an average price of £17,719
  • Audi S4 diesel: 16 cars currently available with an average price of £32,041

We highly recommend thinking about your driving habits before deciding between the different fuel types. Do you generally drive in city conditions or on open highways and motorways? What is your average weekly mileage count?

If you mostly drive short trips, electric cars, plug-in hybrids or petrol cars may be relevant. 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. If you often drive long distances and can't charge, diesel can still be a viable option. Keep in mind that certain countries have bans on high-emission diesel engines entering their cities.

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. Estates, also known as station wagons, are popular with UK consumers. They combine impeccable driving capabilities with the simple advantage of space. Station wagons, SUVs and MPVs tend to be popular with active families.
