Well it looks like the first official pic has been leaked before the Paris Motor Show next week:
Looks just like the concept (from the front at least) except that the first release will be a convertible.
The seats are different from the concept but they still look badass. I wonder how true the rear will be to the concept?
Other things I see different:
The hood on the production car slightly different hood vents
The car on the left doesn't have the aggressive side skirts that the concept had, however the car on the right looks like it does.
Things that are the same:
I still don't see obvious door handles in these pics just like the concept
