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.
