Should your next car be a used Porsche 718?

Are you interested in buying a pre-owned sports car? The Porsche 718 is a solid choice. AutoUncle has 8 used Porsche 718 for sale in UK sourced from different dealership websites and online marketplaces.

How much is a pre-owned Porsche 718 worth?

The pricing range for a used Porsche 718 model at AutoUncle will start at £39,495 and go up to £139,990.

The used car price of an Porsche 718 is determined by a number of factors, the most important of which are manufacturing year, engine size and performance, fuel efficiency, car mileage as well as trim level.

For instance, a more recent model with lower mileage, or a luxury edition with a robust engine, usually garners a premium price than, for example, an older car without special equipment and with many kilometres behind it.

.

What are the available fuel options for the Porsche 718?

There is only one fuel option for the Porsche 718, which is petrol. Right now we have eight cars for sale at an average price of £108,684.

We strongly advise considering your driving habits prior to choosing among the various fuel types. How many miles do you normally clock in a week? Is your driving characterized more by numerous short trips or by extended travels?

If you mostly drive short trips, electric cars, plug-in hybrids or petrol cars may be relevant. For longer daily commutes, a modern electric car is often suitable - especially if you can charge at home or at work. In a few cases with long journeys and limited charging infrastructure, diesel can be a practical solution. Note that there are countries where diesel engines with heavy emissions are forbidden from entering city areas.

Are there different body versions of Porsche 718?

With the cabriolet being the more popular choice, the Porsche 718 is offered in both cabriolet and coupe body styles in the UK. A cabrio or a convertible is a fantastic way to give the driving experience a new dimension. These days, most cabrio models have excellent hoods and weather gear, making them suitable for driving year-round. It’s worth noting that convertibles tend to be heavier than normal cars due to the lack of roof, as thickener is applied underneath the car to strengthen the chassis.
