The oldest and cheapest Mercedes SL43 AMG here on AutoUncle is available for £64,980, and a more recent model with a higher equipment level costs around £109,410.

The price for a Mercedes SL43 AMG is dictated by five main factors: manufacturing year, engine capacity and power, the car's fuel economy, how far the car has already travelled as well as equipment level.

For example, a younger car with fewer miles on the odometer will typically fetch a higher price. Similarly, models at the higher end boasting luxurious features or more powerful engines tend to come with a more substantial price tag than an earlier version with less equipment and higher mileage.

In the process of choosing a fuel type, don’t overlook the importance of your driving habits. How many miles do you drive in a normal week? Do you take many short trips, or do you tend to drive long distances?

For short trips, range is rarely a limitation, so electric, plug-in hybrid or petrol can be fine. For longer daily journeys, consider an electric car, especially if you have the option to charge at home or at work. For longer daily commutes, a modern electric car is often suitable - especially if you can charge at home or at work.
