Great car, engine is quiet. One negative, I do not like the position of the navigation system. Some of the questions is N/A as I only have the car three weeks and am only driving 5 miles to the bus station.
Traded in my 2014 C250 coupe. This is my second C300 sedan. Wow! This car is so nice to drive. Quiet, composed, sporty when you want it to be. I've gotten so many compliments on how beautiful the car is. I didn't get the larger wheels because I wanted the ride to be as soft as possible. Added the $5000 package and it has all the luxury i need. Seats are extremely comfortable, Steering is concise and light. Gear shifts using the paddles are immediate. Fuel economy is pretty good. Averaging 27 mpg combined. If I had one complaint it would be the back seats. They are a bit uncomfortable. Sit a an odd angle and I didn't really feel comfortable in them. Not that I care, really. It's all about the driver seat and that is superb!
