On the hunt for a used Porsche 718 Cayman?

Are you interested in buying a used sports car? The Porsche 718 Cayman is a solid choice. At AutoUncle, we have assembled a collection of 61 used Porsche 718 Cayman cars, each one gathered from an online marketplace or dealership website.

What is the cost of a pre-owned Porsche 718 Cayman?

A used Porsche 718 Cayman costs between £32,990 for the cheapest variant and £73,718 for the most expensive model.

The cost of a pre-owned Porsche 718 Cayman is determined by several factors. Key contributing elements include the year of manufacturing, engine size and performance, fuel consumption of the car, how much the car's odometer reads not to mention equipment.

For example, a younger car with fewer miles on the odometer will typically have a higher price. Likewise, models at the higher end boasting luxurious features or more powerful engines will also carry a heftier price tag than, for example, an older model with more kilometres driven or with a lower equipment level.

How many trim levels are available for the Porsche 718 Cayman?

The Porsche 718 Cayman is available in two distinct equipment variants:

  • Porsche 718 Cayman Edition: Right now you will find 2 cars for sale at an average price of £56,742)
  • Porsche 718 Cayman Sport: 1 car for sale at an average price of £71,718

When comparing the prices of used Porsche 718 Cayman, it is important that you exclusively compare with the prices of cars with the same equipment variant and engine size. If not, you may end up reaching a wrong decision on which car to buy.

What are the most popular fuel types for the Porsche 718 Cayman?

The principal fuel kind for a Porsche 718 Cayman is petrol.

Before you finalize your choice of fuel type, we suggest thoroughly evaluating your driving habits. On average, how many miles do you travel in a week? Do you frequently make short journeys or are your trips generally long?

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. 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.

Are there more body variants of Porsche 718 Cayman?

On AutoUncle, the Porsche 718 Cayman is exclusively offered in the coupe body style. The coupe as a body type prioritises style and sporty driving. Compared to a sedan or an SUV, the chassis tends to be tighter and stronger. This body type is mostly for people without children, who usually travel light. This style is often more expensive than equivalent sedan or hatchback sister models.
