The oldest and cheapest Mercedes C300 here on AutoUncle costs £13,250, while the newest and most well-equipped model costs around £37,518.

A pre-owned Mercedes C300 is valued at different prices depending on primarily five factors: the year of the car, engine capacity and performance, the car's fuel consumption, how far the car has travelled not to mention the vehicle's equipment variant.

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 an earlier version with less equipment and higher mileage.

What equipment levels can you get the Mercedes C300 with?

Here is an overview of the most popular equipment variants for Mercedes C300, sorted by number of cars for sale and their market price:

What are the most popular fuel types for the Mercedes C300?

For the Mercedes C300, petrol is the most favored fuel.

In the process of choosing a fuel type, don’t overlook the importance of your driving habits. Do you primarily use your car to commute, and is the distance 35 miles or fewer each way?

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.

It's important to consider that in some countries, diesel engines with high emissions are prohibited from entering cities.
