The Mercedes-Benz CL borrows its chassis, engine, most of its structure and the front half of its interior straight from the wonderful S-Class saloon; what is there left to tell? 

Well, quite a lot, as it happens. You could question the point of a less practical and more expensive car than the S-class, and we found plenty of people who reckon a Bentley Continental GT or Jaguar XKR are more desirable, but we defy anyone who has spent some time in the CL not to acknowledge that all that goes to making the S-class so fabulous – and a bit more besides – is present in abundance here too. 

The range only comprises three models. Above the 4.7-litre biturbo V8 engined CL500 sit two AMG models, the CL63 AMG with a 5.5-litre biturbo V8 and the CL65 AMG which boasts a 6.0-litre biturbo V12. The CL63 AMG delivers 536bhp and makes the CL feel heroic, the CL65 AMG’s 621bhp and 737lb.ft of torque turning the CL into a monstrously rapid car. The AMG duo are the only CLs to have an obvious direct external competitor: matching them on price, function and performance is the Continental GT, with its V8 and W12 models respectively. 

At around £93k the ‘entry’ CL500 has some competition in the prestigious coupé market, though its rivals differ it in character and appeal. The Porsche 911, Maserati GranTurismo and BMW M6 are rather more sporting and lack the CL500’s comfort, while the Jaguar XKR and BMW 650i are cheaper.

    The DS 5 is hard to pigeonhole but it works as a package. Impressive French-style long-range cruiser, albeit at strong money for an unproven brand

    The 4C improves, and the Spider is a good conversion, but it remains dynamically troubled and absurdly expensive

    More traction and nothing separating Jag's monstrous V8 mouthpiece from your ears. It's the shoutiest, priciest F-Type on sale, but is it the best?
