Ah, so the Metallic is inverted; where it is black, it means not metallic.
But the Roughness also seems wrong to me…the rooftop should be more rough (closer to white) than the metal part of the car…I’d try inverting both Textures…
Oh wait,it looks like the rooftop is not part of the same material…So, invert the Metallic and see if the Roughness needs adjusting…maybe that one is already correct.
