For enhanced safety, the front and rear seat shoulder belts of the Mercedes C Class have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Nissan Maxima doesn’t offer pretensioners for the rear seat belts.
For enhanced safety, the front and rear seat shoulder belts of the Mercedes C Class are height adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Nissan Maxima has only front height adjustable seat belts.
The C300 offers all wheel drive to maximize traction under poor conditions, especially in ice and snow. The Maxima doesn’t offer all wheel drive.
The C Class offers optional Tele Aid, which uses a global positioning satellite (GPS) receiver and a cellular system to get driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Maxima doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies.
Both the C Class and the Maxima have standard driver and passenger frontal airbags, front side-impact airbags, head airbags, height adjustable front shoulder belts, four wheel antilock brakes, traction control and electronic stability systems to prevent skidding.
The C Class comes with a full 4 year/50,000 mile basic warranty, which covers the entire car. The Maxima’s 3 year/36,000 mile basic warranty expires 1 year and 14,000 miles sooner.
The C Class comes with free roadside assistance for as long as you own your car. Mercedes will send help if you run out of gas, need a jump start, lock your keys in or need any assistance on the road. Nissan doesn’t give free roadside assistance for the Maxima.
The C Class’ optional 255/35R18 rear tires provide better handling because they have a lower 35 series profile (height to width ratio) which provides a stiffer sidewall than the Maxima 3.5 SV’s optional 40 series tires.
The C Class is 8.3 inches shorter than the Maxima, making the C Class easier to handle, maneuver and park in tight spaces.
The C Class has .5 inches more rear headroom and 1 inch more rear hip room than the Maxima.
The C Class’ optional folding rear seats are split to accommodate bulky cargo. The Maxima’s optional single piece folding rear seat is not as flexible; long cargo and a passenger can’t share the rear seat.
The C Class’ front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Maxima’s rear power window switches have to be held the entire time to open or close them fully.
In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The C Class offers available headlight washers to keep headlight output high. The Maxima doesn’t offer headlight washers.
To help drivers avoid possible obstacles, the C Class offers optional cornering lights to illuminate around corners when the turn signals are activated. The Maxima doesn’t offer cornering lights.
