While we’re on the subject of mods, how about this mod target for your car roof?
Designed for the Mini (probably as a cheap(er) and replaceable option to BMW’s own customisation), the decal comes in one piece, ready to fit to your Mini or indeed any other car. It’s designed for a white roof, but if you haver a different colour, a version with a white outline is available for an additional £10.
The standard decal retails for £65.99.
