I am the second owner, but I am aware of what panels are painted and what aren't. My trunk still has the original paint, which is starting to fade, which I think is because of the harsher weather conditions from where the car is originally. The overall condition of my car tells me it was parked outside in heat and sun alot.
I am going to get the trunk painted, along with paint corrections wherever required. I am not worried about the resale value as I only commission quality shops for bodywork/paint and use original products.
