Looking for a used Porsche Cayman at an unbeatable price?

Are you thinking of buying a used sports car? The Porsche Cayman is a great pick. There are 166 used Porsche Caymen currently available on AutoUncle, each one collected from an online marketplace or dealership website.

How much does a used Porsche Cayman cost?

A used Porsche Cayman costs between £13,495 for the cheapest variant and £65,300 for the most expensive model.

The cost of a pre-owned Porsche Cayman is determined by several factors. Key contributing elements include what year the car is from, engine capacity and power, the car's fuel consumption, the car's mileage and the trim level of 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 a car from an older model year, with higher mileage and no optional extras.

How many different equipment levels does the Porsche Cayman have?

The Porsche Cayman is accessible in two different equipment options:

  • Porsche Cayman Edition: Right now you will find 7 cars for sale at an average price of £46,164)
  • Porsche Cayman Black Edition: 1 car for sale at an average price of £24,990

As you considers the cost of a used Porsche Cayman, it's fundamental to examine vehicles that have the same engines and features. If you don't, you might draw an inaccurate conclusion about which car to purchase.

What are the available fuel options for the Porsche Cayman?

The most popular fuel type for the Porsche Cayman is petrol.

Fuel options to choose from:

  • Porsche Cayman petrol: 165 cars currently available with an average price of £26,765
  • Porsche Cayman diesel: 1 car currently available with an average price of £13,590

In order to choose the right fuel type, you need to ask yourself the following questions: Do your driving habits lean more towards city streets or open roads and motorways? What is the total distance you drive in a typical week?

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. 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. If you often drive long distances and can't charge, diesel can still be a viable option. Note that in some countries, diesel engines with high emissions are no longer allowed to enter some cities.

Does the Porsche Cayman have multiple body styles?

On AutoUncle, the Porsche Cayman is exclusively offered in the coupe body style. The coupe as a body type prioritises style and sporty driving.

This style is often more expensive than equivalent sedan or hatchback sister models.
