BTW, Hertz is saying they don't match to Sixt so seems like YMMV
Good morning.
The Hertz Status Match program was established to match your current member status with Avis or National / Enterprise. In order to process a status match, please provide a copy or screen shot of your Avis (Preferred Plus / First or President Club), Enterprise (Silver, Gold or Platinum) or National (Executive or Executive Elite) membership card or statement for further review. We are unable to provide a status match for any other programs through Hertz Status Match.
I regret Hertz does not currently match Sixt at this time. I apologize for the inconvenience this causes.
Kind Regards,
