Interested in finding a great deal on a used Mercedes GLC350?

Are you interested in getting a pre-owned SUV? Then the Mercedes GLC350 is a good decision. AutoUncle showcases a total of 38 cars sourced from various dealership websites and online marketplaces.

How much does a used Mercedes GLC350 cost?

A used Mercedes GLC350 costs between £15,490 for the cheapest variant and £23,000 for the most expensive model.

The used car price of an Mercedes GLC350 is determined by a number of factors, the most important of which are production year, engine capacity and power, fuel consumption, mileage not to mention the equipment level of the car.

For example, a newer model with low mileage or a premium version equipped with a high-performance engine generally demands a higher price than, for example, an older car without special equipment and with many kilometres behind it.

How many equipment variants are there for the Mercedes GLC350?

When comparing the prices of used Mercedes GLC350, it is crucial that you only compare with the sale prices of cars with a similar engine and equipment variant. If you don't, you may come to a wrong decision on which car to purchase.

Which fuel variants are most in demand for the Mercedes GLC350?

The Mercedes GLC350 is available with just one fuel type, diesel. There are currently thirty-eight cars available at an average price of £19,006.

We advocate for a careful review of your driving habits before you commit to a fuel type. Is city driving or highway and motorway travel more common for you? What are your average miles driven per week?

If you primarily drive short distances, electric, plug-in hybrid or petrol is typically a good fit. For longer commutes, a newer electric car is a good alternative - especially with access to charging. For longer daily commutes, a modern electric car is often suitable - especially if you can charge at home or at work. Diesel cars can still make sense if you drive very far and don't have access to charging. Note that certain countries have banned high-emission diesel engines from cities.
