Interested in finding a great deal on a used Porsche 911 Turbo S Cabriolet?

What is the cost of a pre-owned Porsche 911 Turbo S Cabriolet?

A used Porsche 911 Turbo S Cabriolet costs between £59,948 for the cheapest variant and £169,995 for the most expensive model.

The used car price of an Porsche 911 Turbo S Cabriolet is determined by a number of factors, the most important of which are what year the car is from, engine capacity and performance, the car's fuel economy, how many miles it has travelled and 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 variants are available for Porsche 911 Turbo S Cabriolet?

The Porsche 911 Turbo S Cabriolet has an equipment variant called Porsche 911 Turbo S Cabriolet Chrono.

When looking for the best car deal for a used Porsche 911 Turbo S Cabriolet, it is important only comparing the sale prices of cars with a similar equipment variant and engine size. Otherwise, you may end up reaching a wrong conclusion on which car to purchase.

Which fuel types does the Porsche 911 Turbo S Cabriolet come with?

The sole fuel type for the Porsche 911 Turbo S Cabriolet is petrol. We currently have twenty-six cars available at an average price of £120,364.

Before you finalize your choice of fuel type, we suggest thoroughly evaluating your driving habits. How far do you usually drive in a standard week? Are your trips more often short ones, or do you tend to travel over long distances?

If you mostly drive short trips, electric cars, plug-in hybrids or petrol cars may be relevant. 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. Diesel cars may still be relevant in some cases with very long journeys and lack of charging options. Note that there are countries where diesel engines with heavy emissions are forbidden from entering city areas.
