What is the price of a used Mercedes SL43 AMG?

The German car is valued at different prices based on primarily five factors: production year, engine size and performance, fuel economy, how many miles the car has travelled not to mention the level of equipment in the car.

For instance, a car that is newer and has fewer miles on the clock will typically command a higher price. In the same vein, models at the higher end, replete with luxurious features or more robust engines, generally come with a more substantial price tag than, for example, an older model with more kilometres driven or with a lower equipment level.
