The AMG C-Class Coupe offers an optional heads-up display that projects speed and other key instrumentation readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Vantage doesn’t offer a heads-up display.
The AMG C-Class Coupe’s front power windows open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Vantage’s power windows’ switches have to be held the entire time to close them fully.
