The 3 Series Sedan (except 320i) offers an optional Side and Top View Cameras to allow the driver to see objects all around the vehicle on a screen. The C-Class Sedan only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

Both the 3 Series Sedan and the C-Class Sedan have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding and available all wheel drive.
