Which C 300 is the Best?

Since there are so many permutations from three body styles and several drivetrains, the only thing we can really recommend is to select the Driver Assistance package from the options. If it saves one accident, it could have paid for itself. Find a Mercedes-Benz C-Class for sale

2020 Mercedes-Benz C 300 vs the competition

2020 Audi A4 -- Polished, packed with tech and updated for 2020. The S4 is a credible alternative to the C 43. The similarly refreshed A5/S5 also goes up against the C-Class coupes and cabriolets.

2020 BMW 3 Series -- Supremely capable, engaging, luxurious and high-quality.

2020 Genesis G70 -- Currently the best car in the Genesis lineup. Plenty of equipment for the money and even some driver involvement.

2020 Jaguar XE -- Has a suspension that every other car company could learn from. It's sinewy, supple, taut, precise and forgiving. The rest of the car is pretty good too.

2020 Lexus IS -- Distinctive styling, smart interior and a generous equipment list. The oldest contender here.

2020 Volvo S60 -- Stylish, safe, well-equipped and comfortable.

Used Mercedes-Benz E-Class -- Going down this route brings more space as well as plenty of luxury and gadgetry that comes with the 3-pointed star. Check out the Mercedes-Benz certified pre-owned (CPO) program.
