The Porsche Cayman is a joy to drive and, if you go for the GTS version, has a fantastic, sweet-sounding six-cylinder engine to match its superb dynamics. If your budget doesn't stretch to the GTS, don't worry: the Cayman 2.0-litre is a fine alternative that still handles superbly, it just doesn't sound as sweet. The Alpine A110 is a seriously good alternative to the Cayman – it's not as fast around a track but great fun on the road.
