For enhanced safety, the front and rear seat shoulder belts of the Mercedes AMG C-Class Coupe 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 Ford Shelby GT350 doesn’t offer pretensioners for the rear seat belts.
The AMG C-Class Coupe’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Shelby GT350 doesn’t offer pre-crash pretensioners.
Using vehicle speed sensors, smart airbags in the AMG C-Class Coupe deploy with different levels of force or don’t deploy at all to help better protect passengers of all sizes in different collisions.

The AMG C-Class Coupe uses gas struts to support the hood for easier service access. The Shelby GT350 uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.
J.D. Power and Associates surveys of service recipients show that Mercedes service is better than Ford. J.D. Power ranks Mercedes fifth in service department satisfaction. With a 59% lower rating, Ford is ranked 24th.
The AMG C-Class Coupe has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Shelby GT350 doesn’t offer a remote starting system.
Unlike the driver-only memory seat and mirrors optional at extra cost in the Shelby GT350, the AMG C-Class Coupe has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The AMG C-Class Coupe’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Shelby GT350’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.
