My initial reaction to seeing the image was elation for a potential NB MX-5, and what I was sure was a keitruck: at first a Daihatsu Midget I MP5, then seeing the shorter face, perhaps a round-headlight Autozam Scrum.
I know not to trust my mind's eye on silhouettes, though, so I defer to the posited Peugeot, Z4, and... Unimog?!!
If this is the case; it's great to see a non-AMG Mercedes, and furthermore, that is the nuttiest addition for GT, and wildest perspective trick in a silhouette reveal I've ever seen. Not sure what I'll do with der Unimog's huge tyres... conquer Big Willow infield? I'm not sure how to stay in there without getting respawned in GT7, much easier to go paddock bashing in 6 and Sport.
In a few months you'll probably tell me that a rectangular car which looks like a Honda Life Step Van is actually a Volvo B10M.
