I designed those Team Lexus Stickers, they looked the nuts
Those stickers were printed on clear static vinyl and when applied they looked ace as they were behind the glass and did not have any adhesive.
Sticker on the inside were better IMO, but if you are using vinyl on the back window may be awkward to remove at a later date.
We are currently running gold on black, looks ace, but dont have au. at the beginning.
