I agree with you Con. I think that keeping it consistent, either all black or all chrome looks best
Re black v chrome grill though, I think the black grill looks better on the 8P but believe the chrome looks better on the 8v. I agree with Johnnyb that the chrome gives it more character that I think it kinda misses with black (well at least in the pics that I've seen).
So yours has a black grill? But with aluminium rails which you'll wrap in black and sunroof from memory? Will look very nice imo - would love to see it when it arrives!
