I purchased a new Toyota C-HR in March. I am very happy with the car but have noticed at the rear corners there is a very fine, thin transparent trim which follows the shape of the black plastic over the wheel arch and then borders the panel joint up to the rear light clusters. I didn’t see it when I collected the car and subsequently only noticed it when I looked closely.

I have returned to the dealership to discuss the issue with them, and they responded positively and showed me a range of C-HRs from 68 reg to brand new, and each one was identical to mine with regard to this very fine film. This would suggest that the car is manufactured like this, something I have never come across before. Is this something I need to be concerned about?
