Eventually the tow-hook mounted license plate flexes/bends and scuff and scratch up the bumper anyway. Friend with one had the license plate pushed in so it made a nice gouge line in the bumper. I thought about it, then looking at his damage, just got the BMW i3 specific licence plate mount. Yes, you have to drill into the bumper, but you are never going to see it - will be behind the license plate forever. The i3 specific frame is nice, contoured to the bumper. The bumper has two small indentations where that frame mounts, and the frame has two small prongs on the back that match up with the indentations, these are used to exactly line up the frame in place. Drill two small holes and use 1&1/2"stainless steel sheet metal screws to screw into the bumper. then attache the licence plate to the frame with short nuts & bolts [ attachment=0]Lic2.png[/attachment]
