What's the used Mercedes C-Class saloon like?

When it comes to a rock-solid premium image, there’s little to beat a Mercedes. After all, who doesn’t want to ride behind that famous three-pointed star? The only problem for the C-Class has always been the stiff competition it faces in the executive car class, namely the Audi A4 and the BMW 3 Series. However, the comfort and relaxed driving experience, not to mention the air of dependability, of this 2014 to 2021 generation of the C-Class have been enough to win plenty of admirers.

Not surprisingly, considering it stretches back so far, it’s the diesel-engined cars that are most plentiful on the forecourts. The 136bhp 1.6-litre in the C200d has enough poke for most, but the 170bhp 2.1-litre C220d feels a little livelier and comes close to matching the smaller engine for economy and CO2 emissions. The thirstier 204bhp 2.1-litre C250d, while admirably brisk, is harder to recommend, as is the later 245bhp 2.0-litre C300d. 

Fuel economy is best served by the C350e plug-in petrol hybrid, C300h diesel hybrid, or C300de plug-in diesel hybrid. However, as with all similar hybrid cars, the headline figures should perhaps be taken with a pinch of salt.

Opt for the entry-level SE trim and you'll find 16in alloy wheels, auto wipers, cruise control, a reversing camera and Mercedes' Collision Prevention Assist Plus system fitted as standard, while inside occupants are treated to a 7.0in infotainment system with DAB tuner, multimedia interface and touchpad, and electric seat height and backrest adjustment for the front seats.

Upgrade to the fleet-friendly SE executive edition and you get heated front seats, Garmin-powered sat-nav, front and rear parking sensors, and 17in alloys. Sport models get LED headlights, a lowered suspension, folding and dimming mirrors, and leather sports seats. The range-topping AMG Line specs include 18in AMG alloy wheels, an aggressive bodykit and sports suspension. 

Those opting for the beefy AMG models also get a bespoke trim for their fire-breathing monsters. The C 43 comes with a bespoke AMG bodykit, brake calipers and details, Artico leather upholstery and red seat belts, while the C63 comes with a mechanical rear axle differential lock and a Nappa leather upholstery. The range-topping C63 S comes with much of the same equipment except for 19in alloy wheels, grey seatbelts and AMG performance seats.

On the road, the C-Class’s dynamic behaviour and ride comfort are a step up from the older variants, even if it’s not quite as sharp to drive as its two major rivals. Where it disappoints is in refinement, with too much road noise and, most noticeably in the diesel variants, too much engine noise making its way back into the interior.

However, the C-Class remains a solid and mostly dependable buy, with plenty of trims, a well-equipped interior and lots of class-leading safety and security kit. Facelifted models from 2018 onwards gained a bigger infotainment screen of 10.3in and additional driver assistance tech.
