1,000 free Lufthansa miles for registering at Sixt ‘Meilenspur’

A new promotion from Sixt and Miles&More to earn 1,000 award miles when registering for Sixt 'Meilenspur'.

I just registered and it worked perfectly for me. The miles have not been credited yet though.

The webpage is in German though so use Google Translate.
