So recently I've installed a Del Perro Police pack, made by the great one and only RangerZ. I took the addon version, considering all my replace slots are taken and I want department variety. 
 

However, here is the issue, I have noticed, and to be fair it annoys me, that the rambar of the Dogde charger (Slicktop and marked), as well of the FPIS (Ford Taurus) in the pack, are white coloured. It sounds like a big ruckus for nothing, but what I find strange is that it doesn't appear on the third car, which is the Tahoe.

 

for better example, see the image.

Solution: Turned DirectX 10.1 to DirectX 11
