2020 Mercedes-Benz C-Class AMG C 43 Sedan Exterior Shown

+205

The 2021 C-Class delivers respectable performance, impressive comfort, and a luxurious cabin loaded with advanced technology. A wealth of options means you can tailor the car to taste, but those options can add up quick. At a certain point, the Benz's traditional rivals start to look like better values. But there's no denying the Benz's attention to quality and the appeal of its elegant, old-school luxury feel.

2020 Mercedes-Benz C-Class C 300 4MATIC 2dr Convertible AWD (2.0L 4cyl Turbo 9A)

I’ve had this car for over a year. I had to order the car to get silver with a red interior and top with the driver assist package. It’s a very comfortable car. I took a 4K mile road trip as soon as it arrived. On the road it got 32 to 33 mpg. The ride is smooth and the acceleration is good. The driver assist package has some nice features. I got it mainly for adaptive cruise control. … Mercedes makes it hard to get and expensive - driver assist requires the navigation package. There have been no mechanical issues in the past year. One complaint is the trunk can only be opened with the key fob or a release inside the car. Another is the ventilated seats are not cooled. They only blow air through the seats that is the same temperature as the air in the car making it a useless feature on a warm day with the top down. Overall I am pleased with this car and plan to drive it many years. I've had the car just over 2 years. There has only been one problem beyond regular maintenance. When putting the top down the cover that closes over the top was not going all the down. The local dealer lubricated the parts associated with lowering the top. That fixed the problem. It has worked perfectly since. Insurance is expensive. Before buying the car I had read that was the case with the C class. It cost more to insure this car than the two cars we had before this one (228i convertible and Golf R). After two years I am still happy with the car and will continue to drive it for many years. Edmunds is asking for an update at 2 years and 9 months. The starter battery had to be replaced. We don't put a lot of miles on the car. Mercedes told us we should drive more. The problem with the cover over the top closing completely came back. This time Mercedes replaced various cables in the top and the top liner. It has worked well since. Both the battery and top repair were under warranty. After almost 3 years I still enjoy driving this car. Edmunds is asking for an update at almost 4 years of owning this car. There have been no problems during the last year. I am still very satisfied with the car. It's been 5 years and Edmunds is asking to update my review. I've had no problems with the car since the last review. It's a low mileage car at 29K miles so far. I am satisfied with the car. After 5 years I usually want something different but I don't feel that way about this car. I will keep it for several more years. It is still beautiful in silver and red.

Love this car

2020 Mercedes-Benz C-Class C 300 4dr Sedan (2.0L 4cyl Turbo 9A)

This is my second c300 and I love this car. It’s not to big but has plenty of room for adults in the back seat. It has great, luxurious options, great acceleration, plenty of space and love that the back seats fold down when you need extra room

Best of both worlds

2021 Mercedes-Benz C-Class C 300 4MATIC 4dr Sedan AWD (2.0L 4cyl Turbo 9A)

I did some pretty extensive research in this class, including the 330i xdrive and A4. After taking each of them on extensive test drives, I decided on the C300 4MATIC with the AMG line. I was very close to taking a great deal on the 3 Series, but in my heart I knew I liked the Mercedes more. It's much smoother, better built, and has better technology. I felt like the 330i's ride was a …
