My white i3 has the 3M blue wrap on the top of the hood, leaving the side edges black. The blue collar around the roundel is stock and is virtually indistinguishable from the color of the wrap that snugs up around it. Also wrapped the front lower corner piece like shown in the picture on dropbox. Also wrapped are three horizontal stripes on the tail: the entire spoiler, the narrow strip that includes the hatch release, and a narrow bar under the bumper. I think the horizontal stripes give the car a wider stance appearance, less tall/boxy looking.
The shark fin antenna on the roof is also wrapped (all but the skinny rod). Great parking lot locator help!
I also added clear protection to the front bumper, and to the top of the rear bumper (the cargo loading area), I also added a black wrap to the front of the side mirrors. The black front on the mirrors gives the i3 a bit more aggressive look from the front (less happy looking), and provides a continuation of the side black stripe from the front tip of the hood, through the side windows, to the tail.
Detail pictures are in the BMW i3 Facebook group, and a few pictures are also in the gallery of the wrapping company at <http://www.smartfilmaz.com/gallery/>. Unfortunately, that gallery seems to be down right now, but I believe my i3 is on page 4 of the gallery.
