It wears the Porsche badge on its snout so, naturally, buying a Cayman will require a hefty initial investment (with no discounts available, either), particularly for our favourite GTS model. If your budget doesn't stretch to the GTS, don't worry – the entry-level Cayman is an excellent driver's car and you can have one for around the same price as the Alpine A110 or Toyota Supra.
Servicing, replacement parts and tyres will all cost a fair bit. Real-world fuel economy isn't brilliant, either, with the Cayman 2.0-litre averaging 34.4mpg in our True MPG tests. The Cayman S 2.5-litre hit an average of just 28.4mpg, which isn't great when you think that's similar to the real-world economy you'll get from a carefully driven GTS 4.0-litre.
So what do you get? Well, the standard Cayman comes with electric windows, air-con, 18in alloy wheels, xenon headlights, and part-Alcantara heated seats. The good news is you don't need to add any options, such as PASM adaptive dampers or the limited-slip differential, to make it drive brilliantly; it's great as it comes.
The Cayman S adds 19in wheels, while the GTS model comes with discreet styling upgrades, 20in wheels, PASM adaptive suspension, a limited-slip differential, sports exhaust and the Sports Chrono Pack.
In the 2020 What Car? Reliability Survey, Porsche finished joint 22nd (out of 31 brands) in the overall manufacturer league table. That's just ahead of Mercedes, but a long way behind Toyota in third, and BMW in ninth. Worse still, the Cayman was the least reliable sports car in our survey.
