Are you thinking of buying a used large sized family car? The Mercedes C320 is a great pick. AutoUncle features 22 avalable cars to choose from, each one gathered from an online marketplace or dealership website.

How much does a used Mercedes C320 cost?

A used Mercedes C320 costs between £1,950 for the cheapest variant and £10,000 for the most expensive model.

A used Mercedes C320 is valued at different prices depending on primarily five factors: the year of manufacturing, engine size and power, fuel economy, how far the car has travelled along with equipment.

For instance, a model that is younger with less miles on the odometer, or higher-end models with more potent engines will generally fetch a higher price than a used model with many kilometres on the odometer and in a simple equipment variant.

What versions of the Mercedes C320 are available based on equipment?

The Mercedes C320 is offered in two separate equipment configurations:

  • Mercedes C320 Elegance: Right now you will find 2 cars for sale at an average price of £3,498)
  • Mercedes C320 Avantgarde: 1 car for sale at an average price of £2,695

While calculating the cost of a used Mercedes C320, it's key to evaluate vehicles with equivalent engines and accessories. If you don't, you might draw an inaccurate conclusion about which car to buy.

What fuel types are available for the Mercedes C320?

The Mercedes C320 is available with just one fuel type, diesel. Right now we have twenty-two cars for sale at an average price of £6,508.

We urge you to take your driving habits into account before settling on a specific fuel type. How many miles do you normally clock in a week? Is your driving characterized more by numerous short trips or by extended travels?

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. Diesel cars may still be relevant in some cases with very long journeys and lack of charging options. Note that there are countries where diesel engines with heavy emissions are forbidden from entering city areas.

What body types is the Mercedes C320 available in?

With the sedan being the more popular choice, the Mercedes C320 is offered in both sedan and stationcar body styles in the UK. Usually fitted with four doors, the saloon or sedan body type has been popular with families for a long time. With its versatile design, the saloon caters to a range of needs, from daily commutes to longer journeys, and remains a symbol of elegance and practicality in the automotive world.
