Auto Trader verdict:
Over the years, Porsche has built some stellar products, but it just goes to show that the closer you fly to the sun, the further you have to fall. Although the latest Cayman looks, drives, handles and stops better than ever, its 2.0-litre flat-four engine is an absolute nail. Yes, the turbo makes it faster and more efficient than the old six-cylinder engine, but it sounds and performs like it was engineered in a kindergarten. Consequently, it undermines every other endearing aspect of what is an otherwise brilliant sports car.
