It’s got a Porsche badge on the nose, so naturally buying a 718 Cayman will require a hefty initial investment (with no discounts), and the Cayman S even more so given the circa five-figure premium it commands over the lower powered, 2.0-litre version.
Servicing, replacement parts and tyres will all cost more than you might expect, too. Worse still, real-world fuel economy is very disappointing: our True MPG tests on the S revealed an average of just 28.4mpg, which is less than you'll get from a supercharged V6 Jaguar F-Type Coupe. Our preferred choice, the 2.0-litre, manages a much more palatable 34.4mpg on our True MPG cycle.
More positively, the Cayman will hold on to its value well, so the costs stack up surprisingly well against rivals such as the Jaguar F-Type Coupe. However, the Cayman does look very expensive next to the Audi TT and BMW M2, even before you consider the more generous amount of standard equipment both of those rivals come with.
Porsche Cayman equipment
Porsche is notorious for giving away very little standard equipment, and this is true of both the standard model and the higher-powered Cayman S. Neither car has Bluetooth, cruise control, sat-nav, parking sensors, or a DAB digital radio as standard. Not only that, but adding these options separately is expensive, with few ‘bundles’ of kit offered to lower the cost.
The problem is that to protect the future resale value of your car, adding most of these items is essential – so you may have to bite the bullet and add them regardless.
Porsche Cayman reliability
Assessing the reliability is tricky, because Porsche doesn't feature in most reliability surveys. As well as this, the engines are new so they don't have a track record of proven dependability.
In our most recent used car reliability survey, Porsche finished second from bottom of the 37-strong list of manufacturers, although most of the cars in the survey are no longer on sale.
Every Cayman comes with a three-year, unlimited-mileage warranty, but like most cars of this type it will chew through consumables like tyres and brakes at a rate of knots.
Porsche Cayman safety & security
There’s no Euro NCAP crash data available on the Cayman, but all version come with six airbags and the option of automatic emergency braking. The standard steel brakes are more than up to the job of frequent stops from high speed, but Porsche offers fade-free carbon-ceramic discs as an option. The latter is only worth considering is you plan to attend track days.
You have to pay extra to add Isofix fittings to the passenger seat of the Cayman, while blindspot monitoring and speed limit display are also on the options list.
Security experts Thatcham awarded the Cayman a maximum five-star rating for resisting theft, and four stars for withstanding being broken into.

Entry-level Caymans come with a 2.0-litre turbo petrol engine, xenon headlights, LED running lights, 18in alloys, part-electric seat adjustment, part-Alcantara upholstery, air conditioning and a 7.0in touchscreen. You get a six-speed manual gearbox as standard but can pay to add an optional seven-speed PDK auto.
718 Cayman S
This range-topping S model gets the more powerful 2.5-litre petrol engine, 19in alloys, a part-leather interior and sports seats, plus extra styling details over regular 718 Cayman. You'll still want to add plenty of options, though.
