The Mercedes C-Class was brought up to date in 2011, with a subtle but thorough overhaul that kept it on par with its main compact executive rivals the BMW 3 Series and the Audi A4. More stylish grill and bumpers make it stand out and feel modern, while the interior got a totally redesigned dashboard that's made of higher quality materials, with a slick layout complete with integrated media screen. You can get the C-Class as either an executive saloon, a more practical estate car or a speedy-looking coupe, with the four-door executive accounting for the bulk of all sales. The saloon comes in four main specifications – the entry-level Executive SE, the sportier AMG Sport and AMG Sport Plus, then the top-of-the-range AMG, with the C63 AMG performance model by far the fastest in the range. All models come well equipped, fitted with air-conditioning, Bluetooth connectivity and alloy wheels fitted as standard across. All the petrol and diesel engines on offer are efficient, with standard-fit BlueEFFICIENCY technology and stop-start helping to make the C-Class one of the most efficient premium cars that you can buy in the UK. The most environmentally friendly model is actually the twin-turbo C220 CDI diesel, which can return 68.9mpg in combined fuel economy and only emits 109g/km of CO2. Potential buyers should be aware that 2014 will see the arrival of the latest all-new Mercedes C-Class, so it may be better to wait for the new model or buy the current one second-hand and save some cash.
