Coarse engine and harsh AMG suspension

The car is gorgeous. I got it for my wife and she loves its looks over the BMW 3 series and Audi A4 which she thought looked too plain and masculine. It has a striking and sporty exterior, especially with the black roof and trim paired with white color. The tan interior is light and airy and classy. Wired CarPlay is meh but I can live with it. But my wife isn’t a car person and only had an old Honda before.. The C300 drivetrain and suspension are incredibly unrefined. The coarse 4 cylinder engine sounds like pebbles and sand in a cement mixer. The AMG suspension crashes on any road imperfection and makes the car feel like it’s going to shake apart and break. My wife drives it so slowly in it because she thinks she’s going to damage her lovely car driving on lousy LA streets with the suspension crashing on ruts and potholes. Unless you’re on a glass smooth road with the music playing loudly, this car is a terrible driving experience.

There is too much plastic in this car. The interior was peeling off after a while. I am very disappointed and unhappy with this car. Before buying it, I read so many negative comments about it but I did not pay attention and now I realized that others were right about this car. Very unreliable piece of plastic.

I've had the MB since 2021 and I'm still happy with my purchase. The car has nice safety features, good handling, and gets alot of compliments from other drivers... after driving the car for 3 years with no issues. There was a battery problem. But i got it fixed for free under my warranty. and its been good. I def would recommend this vehicle if your looking. I just wish you didnt have to pay to use the Mercedes me app.

I enjoy my vehicle . It’s smaller (interior) (height) than previous autos owned but very nice. Gas mileage is median Maintenance I find expensive. Love all the “bells and whistles”
