Are you considering getting a used SUV? The Mercedes GLS400 is a solid choice. AutoUncle features 22 avalable cars to choose from sourced from various dealership websites and online marketplaces.
A used Mercedes GLS400 costs between £44,995 for the cheapest variant and £68,990 for the most expensive model.
The used car price of an Mercedes GLS400 is determined by a number of factors, the most important of which are year of production, engine size and power, the car's fuel economy, how many miles it has travelled along with the level of equipment in the car.
For example, a younger car with fewer miles on the odometer typically costs more. Likewise, models at the premium end with luxurious features or potent engines tend to come with a more substantial price tag than, for example, an older model with more kilometres driven or with a lower equipment level.
The most popular equipment variants for the Mercedes GLS400 are:
When examining the market value of a used Mercedes GLS400, it's imperative to examine vehicles sharing identical trim level. Otherwise, you might draw an inaccurate conclusion about which car to buy.
The predominant fuel variant for the Mercedes GLS400 is diesel.
It's essential to take into account your driving habits when determining the right fuel type. On average, how many miles do you travel in a week? Do you frequently make short journeys or are your trips generally long?
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. 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. For those who drive long distances and don't have access to charging, diesel cars can still be an option. Be aware that in a number of countries, cities have implemented bans on diesel engines with high emissions.
On AutoUncle, the Mercedes GLS400 is exclusively offered in the SUV body style. Sport Utility Vehicles, or SUVs, are some of the most popular cars on the market today, thanks to their versatile style and elevated ride height.
