Thinking about buying a used Porsche 718 Cayman?

Are you thinking of buying a used sports car? The Porsche 718 Cayman is a solid choice. AutoUncle showcases a total of 61 cars, each one collected from an online marketplace or dealership website.

How much does a used Porsche 718 Cayman go for?

A used Porsche 718 Cayman costs between £29,995 for the cheapest variant and £74,490 for the most expensive model.

The used car price of an Porsche 718 Cayman is determined by a number of factors, the most important of which are year of production, engine size and power, fuel consumption, car mileage and the equipment level of the car.

For example, a newer model with low mileage or a premium version equipped with a high-performance engine generally demands a higher price than, for example, an older car without special equipment and with many kilometres behind it.

How many different equipment levels does the Porsche 718 Cayman have?

As you considers the cost of a used Porsche 718 Cayman, it's fundamental to evaluate vehicles with equivalent engines and accessories. Otherwise, you might draw an inaccurate conclusion about which car to purchase.

What are the fuel options for the Porsche 718 Cayman?

For the Porsche 718 Cayman petrol stands as the only fuel type available. We currently have sixty-one cars available at an average price of £48,145.

Your current driving habit is a determining factor when it comes to picking a fuel type. Do you frequently drive within city limits or on broader highways and motorways? What's the average number of miles you drive weekly?

If you drive mostly short distances, range is not crucial - so electric, plug-in or petrol are obvious choices. For daily long journeys, electric cars make the most sense if you can charge easily. 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. Bear in mind that diesel engines emitting high levels of pollution are not allowed in cities in a number of countries.

Does the Porsche 718 Cayman have multiple body styles?

On AutoUncle, the Porsche 718 Cayman is exclusively offered in the coupe body style. Style and sporty driving take centre stage in a coupe, and this body type tends to have a tighter and stronger chassis than, for example, a sedan or an SUV. The model is best suited for people without children and others who travel light. It is usually more expensive than equivalent sedan or hatchback sister models.
