On the hunt for a used Mercedes GLB220?

Are you considering getting a used SUV? The Mercedes GLB220 is a great pick. There are 98 used Mercedes GLB220s currently available on AutoUncle compiled from numerous dealership websites and online marketplaces.

What is the cost of a pre-owned Mercedes GLB220?

A used Mercedes GLB220 costs between £20,490 for the cheapest variant and £35,650 for the most expensive model.

The used car price for a Mercedes GLB220 varies according to five main factors: the year of the car, engine capacity and power, fuel consumption, how many miles it has travelled along with the vehicle's equipment variant.

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 an earlier version with less equipment and higher mileage.

How many trim levels are available for the Mercedes GLB220?

When assessing the price of a used Mercedes GLB220, it's essential to evaluate vehicles with equivalent engines and accessories. Otherwise, you might draw an inaccurate conclusion about which car to purchase.

Which fuel options are available for Mercedes GLB220?

The Mercedes GLB220 only exists with one fuel type and that is diesel. We currently have ninety-eight cars available at an average price of £28,609.

We strongly advise considering your driving habits prior to choosing among the various fuel types. Is your driving primarily through city traffic or along open highways and motorways? How many miles do you rack up in an average 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 may still be relevant in some cases with very long journeys and lack of charging options. Take into account that several countries restrict high-emission diesel engines from their city zones.

The Mercedes GLB220 only comes in the SUV body type in the UK. SUV is short for Sport Utility Vehicle, and this is easily one of the most popular cars on the market today. The style is versatile, and the ride height is higher than traditional cars, which is a key selling point.
