Just a note of caution.
The (canvas) tonneau that came with my ivory-colored VS is in two layers. The upper side is tan, but the under side is black canvas.
I frequently drive with the passenger side attached and, since new, this has always left black marks along the upper edge of the passenger door and on the front edge of the vinyl-trimmed dash (which I have to continually scrub off.) The tonneau was delivered from the canvas shop that way - it wasn't dyed after the sale. And it's now seven years later.
So, maybe leave well enough alone? I've never seen a white cover on a silver car, but it looks pretty nice in your photo.
