Looks like the front just got changed - and that's it.
To be honest I wasn't expecting anything radical. Mercedes had long before announced that the next generation Sportcoupe would be based on the W203 chassis, so it was obviously going to be a low-investment product from the start.
In Europe, especially in Germany, the C-Class Sportcoupe was actually pretty popular amongst younger buyers. Basically there is still a demand out there for it, so I am guessing this is the reason Mercedes is continuing the car.
I always found the C-Class Sportcoupe to be somewhere in the middle in terms of looks. It's not beautiful, but it's not ugly either (especially the facelift version).
With the proper rims and colors, it could turn heads.
