To be perfectly honest, I would say there are traces of imprefections.
But for me it is understandable because, it is, after-all, a man-made car, not machine produced.
So sometimes humans err.
I have not checked the paint inside my engine bay, but I would understand they do not paint it (might save 1-2 kg
But to give you an example I found a small pieces of masking tape inside the passenger door hinge
So yes, if you want to nitpick, you can.
People would say for that amount of money, it should be perfect...
I would slightly disagree; yes for that money for a mass produce car (A4, X6) I would expect perfection.
But for a handbuilt, limited volume car like the 4C, I understand that the money rather goes is the conception and the technology of the car rather than in the thickness of the pain
