On the hunt for the popular Mercedes S350L used?

Are you thinking of getting a used luxury car? Look no further than the Mercedes S350L - an excellent choice! AutoUncle has 47 used Mercedes S350Ls for sale in the UK sourced from different dealership websites and online marketplaces.

How much does a used Mercedes S350L cost?

A used Mercedes S350L costs between £6,990 for the cheapest variant and £51,990 for the latest and most well-equipped model on AutoUncle.

There are five main factors which have an impact on what a pre-owned Mercedes S350L might cost: what year the car is from, engine capacity and power, the car's fuel efficiency, the car's mileage as well as the trim level of the car.

As an example, a newer model with fewer miles covered, or a high-end version boasting a potent engine, often fetches a top-tier price than a car from an older model year, with higher mileage and no optional extras.

What equipment levels does the Mercedes S350L offer?

When looking for the best car deal for a used Mercedes S350L, it is essential only comparing the sale prices of cars with the same equipment variant and engine size. If not, you might end up reaching a wrong conclusion on which car to buy.

What fuel configurations can I choose from for the Mercedes S350L?

The leading fuel choice for the Mercedes S350L is diesel.

Fuel types for Mercedes S350L:

  • Mercedes S350L diesel: 46 cars currently available with an average price of £24,063
  • Mercedes S350L petrol: 1 car currently available with an average price of £9,490

It's essential to take into account your driving habits when determining the right 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?

If your trips are mostly short, electric, plug-in hybrid or petrol may make the most sense. For daily long-distance driving, the electric car is often ideal - especially with a charger at home or at work. 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. If you often drive long distances and can't charge, diesel can still be a viable option. Remember that diesel engines with high emissions are prohibited from entering cities in various countries.
