I`ve had 2 cars w/ vinyl roofs, never again...They LOOK good , but...tend to leak in under, at least gets moisture in under and rusts out...You`ve got to REALLY get it water proof/moisture proof on to the roof...or you`ll have future problems....
I`d paint the roof different color if you want two tone , using the chrome trim ( for the vinyl) for break point....
just my .02
