Looking for information on a used Mercedes GLC350?

Are you considering buying a used SUV? Then the Mercedes GLC350 is a good decision. AutoUncle features 47 avalable cars to choose from gathered from numerous dealership websites and online marketplaces.

How much does a used Mercedes GLC350 go for?

The oldest and cheapest Mercedes GLC350 here on AutoUncle costs £17,000, and a newer model with a more advanced trim costs around £24,490.

The German car is being offered at different prices relying on primarily five factors: year of production, engine size and performance, fuel consumption, how many miles it has travelled along with equipment.

Your driving behavior is an important aspect to consider when selecting a fuel type. How many miles do you drive in a normal week? Do you take many short trips, or do you tend to drive long distances?

For shorter trips, electric cars, plug-in hybrids and petrol cars are great. For longer commutes, an electric car is often the best choice - especially with charging options 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 can still make sense if you drive very far and don't have access to charging. Note that there are countries where diesel engines with heavy emissions are forbidden from entering city areas.
