Currently, the prices for a pre-owned Mercedes 300 start at £7,000 and go up to £64,534.
A used Mercedes 300 is being offered at different prices determined by primarily five factors: the year, engine size and performance, the car's fuel consumption, vehicle mileage together with the trim level of the car.
For instance, a more recent model with limited mileage, or a premium variant featuring a powerful engine, typically commands a higher price than an earlier version with less equipment and higher mileage.
Here is an overview of the most popular equipment variants for Mercedes 300, sorted by number of cars for sale and their market price:
While evaluating the cost of a pre-owned Mercedes 300, it's crucial to analyze vehicles having the same engines and equipment. If you don't, you might draw an inaccurate conclusion about which car to acquire.
The principal fuel kind for a Mercedes 300 is petrol.
Available fuel options for Mercedes 300:
Your driving tendencies should play a significant role in your fuel type selection. Do you generally drive in city conditions or on open highways and motorways? What is your average weekly mileage count?
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. For longer daily commutes, a modern electric car is often suitable - especially if you can charge at home or at work. Despite the rise of electric cars, diesel can still be useful for long journeys and lack of charging options. Bear in mind that diesel engines emitting high levels of pollution are not allowed in cities in a number of countries.
The Mercedes 300 comes in various body types, stationcar being the most popular. In the UK, estates, commonly referred to as station wagons, are in high demand due to their perfect blend of driving prowess and generous space. Active families often gravitate towards these, as well as SUVs and MPVs, for their versatility.
