The Ghibli has standard Anti-Whiplash Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash.

The AMG C63 Sedan doesn’t offer a remote starting system.
The Ghibli’s instruments include an oil pressure gauge and a temperature gauge – which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The AMG C63 Sedan has neither an oil pressure gauge nor a temperature gauge.
