Now that they replaced the horizontal streak with the vertical grille and made the front bumper more aggressive-looking, the GT S looks much better to me. The original grille makes the headlights look too slanted IMO.
The GT S now is the best-looking of all the Mercedes GTs to me. The bodywork on the GT R and GT C is too aggressive for the GT, and the rear vent between the taillights doesn't help either. I don't like the original grille on the base GT. The black rims suit the GT S very well, though I'd prefer the car in matte or metallic grey. But the GT S is still nowhere near the SLS AMG in terms of aesthetics.
And I still can't figure out why somebody would need 4 air conditioning vents at the centre console.
