Mercedes SLK or baby SLS AMG spy shots

This Mercedes SLK spy shot could also be a baby SLS AMG first look, according to World Car Fans.
The spy shot, similar to previous mules seen testing, was originally considered to be the 2012 Mercedes SLK, but since announcements that a smaller SLS AMG will be produced, that may not be the case.

The idea is that what was once destined to be the stuff of the SLK could in fact be dedicated to the new, smaller SLS AMG, which will appear in the product line-up above the SLK55 AMG, much like the Gullwing is placed above the SL63.

Don’t expect the baby SLS AMG to be a smaller version than the current one, as rumours say that the gullwing doors will be replaced by a more economical option.
That doesn’t help to identify these spy shots, then, because if we were looking for the signature doors, we clearly have to reconsider.
Alternatively, these spy shots could just be the new SLK redesigned in a more classic style.
We can’t say though, that the idea of the baby SLS AMG from the guys at WCF isn’t tantalising all the same.
