What is a functional US license plate holder for Touring’s?

Any ideas?

For the rear plate you can use the same holder that's used by pretty much all BMWs.

I bought this one:

Quite correct, or if you prefer you can always make a crazy contraption with tiny nuts and bolts that are glued on.

That one, or an OE BMW one, whatever is more readily available to you.
