factory black on red interior

Yeah,the ad says its a factory black car but i see lots of red showing through the black on the passenger side door...love the red interior

I noticed the red showing through as well. I wonder if that's over spray from the factory when they painted the interior of the door? I am getting more and more curious about the process and the order in which things were done at the factory. Would be neat to know.
I agree, the red interior is cool. The black on red is such a strong contrast. I like also the silver on red and red on red dusters.
