The price of a used Porsche 911 GT3 ranges from £79,995 for the cheapest model to £219,990 for the latest and most well-equipped model.

The German car is valued at different prices relying on primarily five factors: the year of manufacturing, engine size and performance, the car's fuel consumption, the car's mileage along with 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, for example, an older model with more kilometres driven or with a lower equipment level.
