The Mercedes E-Class Cabriolet didn't appear in our latest Driver Power satisfaction survey, but Mercedes posted a disappointing result overall. The independent safety body Euro NCAP hasn’t tested the convertible E-Class, so assessing its protective qualities is tricky – though the E-Class saloon posted an excellent result when it was tested.

Mercedes E-Class Cabriolet reliability

The latest E-Class didn't appear in our 2020 Driver Power results but the previous model had a good reputation for dependability. It held its value well as a result, and at least on the surface, this version looks to be even better built.

Mercedes as a brand came 28th out of 30 manufacturers – by no means stellar result. A disconcerting 16.5% of owners reported a problem with their car in the previous 12 months, which is a higher than average figure. Running costs were also considered to be on the high side, with insurance premiums, fuel economy and servicing contributing towards this aspect. Mercedes did do well where design and performance were concerned, while comfort also garnered positive reports.


It's unlikely Euro NCAP will crash-test the E-Class Cabriolet, but the saloon model on which it’s based scored the full five stars, with an impressive 95% for adult occupant protection. It certainly shows the Mercedes is built on strong foundations, and the Cabriolet shares all the latest safety know-how and technology of the saloon, including a system designed to help avoid crashes by assisting with your steering.

All E-Class Cabriolets come with an active bonnet, too, which pops up in the event of a collision, protecting pedestrians from hard engine parts. Autonomous emergency braking is also standard, and this scans the road ahead for potential obstacles, warning you of their presence and applying the brakes automatically if you fail to take action.
