But if you compare the popular 2021 BMW 3-Series vs. Mercedes-Benz C-Class, which is the better vehicle overall? While the 3-Series may have its share of fans, the 2021 Mercedes-Benz C-Class offers unparalleled quality.

C-Class vs. 3-Series: Performance

C-Class vs. 3-Series: Features

Both luxury models offer the type of upscale design and technology that you’d expect from a leading manufacturer, including genuine wood trim and power-adjustable seating with memory. However, the Mercedes-Benz C-Class interior offers some exclusive technology that sets it apart from the competition:

  • HANDS-FREE ACCESS® is standard in the C-Class, but requires an upgrade in the 3 Series. This handy feature adds major convenience to your daily errands, especially when you’ve got your hands full in Ames.
  • ATTENTION ASSIST® monitors your driving performance with over 70 different parameters, and it detects drowsy and fatigue driving to keep you alert on the roads.
  • The 2021 C-Class Sedan comes standard with a 12.3-inch central touchscreen display and a 12.3-inch digital gauge cluster. The 3 Series has a 8.8-inch display, which is much more compact in size.

Audi A4 vs. BMW 3-Series vs. Mercedes-Benz C-Class
