Mercedes C-Class Coupe review - Reliability and Safety

Whether its petrol or diesel powered, the mechanicals are all tried and tested in the C-Class Coupe so there shouldn’t be any nasty surprises. Meanwhile the interior feels built to last thanks to its high quality plastics.

That’s what you’d think anyway. Although the C-Class Coupe hasn’t made an appearance in Driver Power survey yet the Saloon has – it finished a credible 43rd out of 150 cars with owners praising performance and comfort. However, owners weren’t impressed with the reliability and some of those high quality plastics aren’t as resilient as they initially seem. Generally though the C-Class Saloon is a reliable car and scores better than the BMW 3 Series Saloon so you can expect a similar story with the Coupe. 

Just like the Saloon, the Coupe is a very safe car – seven airbags, a driver tiredness monitor and tyre-pressure warning all come as standard. It’s been given a five-star Euro NCAP crash test rating.

Buyers can add hi-tech options like the £2,300 Driver Assistance Pack, which brings blind-spot warning, lane departure assist and adaptive cruise control. Other options include an £825 head-up display and £545 Active LED lights with cornering function and high-beam assist.

Warranty 

Mercedes gives a three-year, unlimited mileage warranty with the C-Class range and is identical to the package supplied with BMW models, but goes one better than the Audi warranty, which limits cover to three years and 60,000 miles.

Servicing 

Since the late 1990s, Mercedes has worked on a condition-based servicing system and the C-Class Coupe is no different. As such, how often your car will be in the dealership will be down to driving style, and the raft of on-board sensors will let you know when an inspection or service is due.

Like the Saloon, for either a one-off fee or a series of monthly payments from as little as £1 (up to £40 for the AMG C 63), Mercedes-Benz Service Care guarantees owners the price of parts and labour for up to four years to protect against inflation. Service Care covers the cost of all recommended service items, including fluids, filters and spark plugs.
