Edmunds Rating
The C 300 Cabriolet flatters its occupants with all the trappings of a modern Mercedes. Its well-crafted interior and advanced technology are at the top of the class. But when fully optioned, it can be more than a bit expensive. And some of those options, such as the AMG Line package and larger wheels, do more harm than good.

Mercedes' new S-Class certainly sets new standards for luxury and opulence. But you know, you might not be able to afford a six-figure executive sedan with facial recognition and a fingerprint scanner. If so, you might want to consider the 2021 Mercedes-Benz C-Class. Available in sedan, coupe and convertible body styles, the C-Class is a versatile small luxury car that offers an appealing mix of comfort, performance and top-notch construction.

But this current-generation C-Class — it dates back to the 2015 model year — is getting on its years, and it lacks the newest Mercedes infotainment interface. As such, the A-Class and the E-Class — the two vehicles that bookend the C-Class in terms of price and size — feel more modern and up-to-date. Check out our Edmunds Expert Rating for the full rundown of this Merc's hits and misses.

Which C-Class does Edmunds recommend?
Any of the AMG models will give you the thrills you'd expect of a sport sedan, but consider sticking with the standard C 300. It has a decent amount of power and the money you save with it means you can spend more on the C-Class' optional extras if you want. The Premium package is a good place to start. The Driver Assistance package is comprehensive without being overly pricey, though it also requires adding the Multimedia package.

Mercedes-Benz C-Class vs. the competition
2021 Mercedes-Benz C-Class
2021 BMW 3 Series
Mercedes-Benz C-Class vs. BMW 3 Series
So long has the C-Class versus BMW 3 Series rivalry lasted that pictographs depicting the struggle were found in an unearthed Egyptian tomb believed to be built during the 12th dynasty. The most recent volley in this eternal conflict was fired in 2019 when BMW last redesigned the 3 Series. The 3 Series and the C-Class are pretty evenly matched but stand as only midpack models in our rankings of small luxury sedans.
Mercedes-Benz C-Class vs. Audi A4
Audi is content to let Mercedes and BMW duke it out while its own compact quietly sits near the top of our rankings of the best small luxury sedans. The Audi A4 was redesigned in 2017, but constant updates mean that every new A4 is better than last year's. We commend the A4 for its tech-forward interior design, high levels of comfort, and roomy, adult-friendly cabin. With standard all-wheel drive and a smattering of included driving aids, the Audi offers surprising value too.
Mercedes-Benz C-Class vs. Mercedes-Benz A-Class
The Mercedes-Benz A-Class is perhaps the strongest reason not to buy a C-Class. It's smaller and comes with front-wheel drive by default, but we think the A-Class bests its bigger brother in a variety of ways. Introduced just a couple years ago, the A-Class has a more comprehensive set of tech features, and the infotainment system's MBUX interface is unquestionably superior to the C-Class' COMAND unit.
