Looking for a used Mercedes GL350?

Are you thinking of getting a used SUV? Look no further than the Mercedes GL350 - an excellent choice! AutoUncle showcases a total of 21 cars compiled from various dealership websites and online marketplaces.

How much is a pre-owned Mercedes GL350 worth?

Currently, the prices for a pre-owned Mercedes GL350 start at £6,495 and go up to £21,995.

A pre-owned Mercedes GL350 is being offered at different prices relying on primarily five factors: year, engine capacity and performance, fuel efficiency of the car, how far the car has travelled together with equipment level.

For example, a newer model with fewer miles recorded, or a more luxurious variant with 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 levels does the Mercedes GL350 offer?

The Mercedes GL350 has an equipment variant called Mercedes GL350 AMG.

As you examine the price of a used Mercedes GL350, it's necessary to examine vehicles that have the same engines and features. If not, you might draw an inaccurate conclusion about which car to buy.

Which fuel types does the Mercedes GL350 come with?

The Mercedes GL350 exclusively uses diesel as its fuel. We currently have twenty-one cars available at an average price of £14,105.

Before making a choice between the different fuel types, it's important to analyze your driving habits. On a regular week, how far do you drive? Do you engage in many brief trips, or are your drives generally longer in distance?

If you drive mostly short distances, range is not crucial - so electric, plug-in or petrol are obvious choices. For daily long journeys, electric cars make the most sense if you can charge easily. 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. Diesel cars can still make sense if you drive very far and don't have access to charging. It’s worth noting that diesel engines with high emissions are banned from entering cities in certain countries.

In which different body variants are the Mercedes GL350 available?

The Mercedes GL350 only exists in the SUV body type in the UK. SUV stands for Sport Utility Vehicle and represents one of the most sought-after car types in today's market.
