Porsche 718 Cayman review - Reliability and safety

The current 718 Cayman and Boxster didn’t make it onto our list of the best cars to own, which is based on owners’ feedback from our most recent Driver Power customer satisfaction survey. We still expect reliability to be strong for these cars, although they are likely to go through consumables faster than the average car, especially if you use the car's performance on a regular basis.

As a brand, though, Porsche is a consistently strong performer in the Driver Power survey results, and earned itself the top spot in our best manufacturer rankings in 2023, 2022 and 2021.

Due to the niche nature of the 718 range, Euro NCAP won't conduct its independent crash tests on the coupe. It does come loaded with airbags and safety kit, but adaptive cruise control is a pricey option.

Warranty

Every Porsche comes with a three-year unlimited mileage warranty, which actually trumps sister-brand Audi’s three-year/60,000-mile guarantee. As with rivals, you can pay to extend your Cayman’s warranty with a variety of plans stretching long into the future. 

Servicing

Porsche tends to fare well for owner satisfaction, although two-year service intervals mean that hopefully you won't need to visit a Porsche centre that often. And with only a handful of Porsche Centres across the UK, that at least means you won't have to make the potentially long trip all that often.

When the time does come to look after your Cayman it won’t be cheap, though, as a minor service can cost over £500. A major service is even more of a sting at over £600. A simple brake fluid change will cost about £100.
