Mercedes C300 – All you need to know

The brand new C300 offers a 2.0L 4-cylinder mild-hybrid powertrain that perfectly balances superior efficiency, class-leading power, and great all-around sophistication. Older C300 models used to come with a 3.0L 6-cylinder engine which was more exciting, but nowhere near as efficient nor sophisticated.

The C300 is actually one of the best-sold premium cars on the entire planet while also being the best sold Mercedes sedan out there. The C300 looks incredibly premium and it separates itself from its competition because it oozes class and sophistication a lot more than the Audi A4, the BMW 3-Series and the Lexus IS.

The C300 does suffer from issues such as oil leaks, electrical issues, and increased levels of vibrations while driving. Value-wise, the new C300 is a hands-down class leader because it is more luxurious, comfortable, and desirable.

All newer C300 models with automatic 7-9 speed automatic gearboxes that are sophisticated and fitting for the C-Class. No C-Class models come with the 4MATIC AWD system from the factory, but you are able to option it out for around $2,000.

All C-Class models come with RWD from the factory but you can upgrade to the 4MATIC model for an additional $2,000. Older C-Class models utilized a more archaic but arguably more interesting 3.0L 6-cylinder engine which offers between 200hp and 250hp.

This engine is not nearly as economical as the new 2.0L but it does feel more substantial. Automatic gearboxes found on older C300 models are better than the ones offered in the A4 but not as good as those offered in the BMW 3-Series.

Chassis-wise, the C300 is tuned for comfort above everything else and that is rather obvious the moment you take the wheel of the C300. Some people deem it to be overly senior-friendly while others believe that a C300 should be comfortable and as stately as possible.

The C300 can also be had in coupe, convertible, and estate form. The coupe version is a lot more dynamic looking and youthful while the cabriolet is mostly popular with women. The estate version is not all that popular outside Germany, but it is the most useable and practical option of the bunch.

Mercedes C300 – Value and practicality

The brand new 2022 C300 costs around $43,000 and the price tag can go a lot higher than that if you option it out completely. All luxury Mercedes sedans are known to plummet in value in the first 5 years of ownership which is more or less a standard for the class.

Practicality-wise, the C300 is decent but nowhere near class-leading in most regards. Seating space is enough for four larger adults while the cargo space is on the lower end, especially when compared to the Audi A4.
