Merc must have a test facility somewhere in Al Quoz as I often see test fleets heading out of there onto Al Khail road.It's not that hidden really - mahoosive DAIMLER sign on top of the building at the SZR-side of Jebel Ali kind gives it away. Yes, that's the corporate HQ but also houses the test facility.
JLR has a test facility here too, but I'm not allowed to say where
Googled the i3, seems the rear lights/hatch are different. Camo is the same though??http://www.caradvice.com.au/147571/bmw-i3-prototyp...
