Parkers overall rating: 4.5 out of 5 4.5

The CL has a sometimes puzzling array of buttons and switches inside, and that's even with most functions accessible within the COMAND system (Cockpit Management and Navigation Display). Owners will need to spend time getting used to how various features are activated, but after a few times using each one it should become much easier. The AMG versions of the CL have brushed stainless steel pedals, AMG instrument cluster and a special analogue clock set in the dashboard, adding an extra feel-good factor to the whole experience.

Visibility is pretty good, although the over-the shoulder view is a little compromised by the tapering roof line. A parking aid is standard.

The AMG versions of the CL come with electrically adjustable seats, closing aids for doors and boot lid, 'doorhold' system (which keeps the door open in any position rather than having two or three set positions) and the front seats are heated. Customers can choose dynamic front seats (which vary the level of support in the side bolsters when cornering) with four massage functions also included.

Noise levels are low, even on 20-inch wheels, although there's just the right level of engine noise under hard acceleration to keep enthusiasts entertained. The CL is designed to travel great distances without being taxing on occupants, a job it does very well.
