I think the OEM silver or aftermarket chrome looks great on the roadster. And in fact, it's fairly common for a roadster to have a silver windshield surround, but I just don't like that look on the coupe. It takes away from the lines of the car, IMO I should say, it's more of a distraction from properly seeing the lines of the car. I have a ubiquitous black XF and painted the surrounds body colored. I still have the silver surrounds, but I will likely never go back to those.
If I was you, I'd probably go with the body colored surrounds. No offense to anyone on this board who fits the following description, but a chrome surround on a fixed top sports car is a bit too old man for me. Next thing you know, you;ll be starting a thread about what color landau roof to put on the car!
