Quick Thoughts
While I haven’t rented often rented via Sixt, I’ve recently been finding some solid deals on rentals via Sixt. I’ve also been consistently seeing targeted Capital One Shopping offers for 30% or more back at Sixt (I received such an offer in a couple of emails just today), up to 45% back. That’s certainly made it worth booking a couple of Sixt rentals, so I could see the potential for a nice stack with this offer.
That said, I usually avoid paying for car rentals with an Amex because of Amex’s inferior rental car coverage. That said, given the savings in this case, it might be worth paying a little extra for coverage to get a good stack.

Perfect for when you want to rent a car in Europe, then experience scams where they try to send you to collections over un-enforceable ‘citations’ or ‘damages’ without proof or the ability to appeal, etc. (just say no)
Sorry for being late at the party but I am very sure that stacking is not possible because Amex won’t payout the $100 if you didnt use the registered Amex card for payment.
But i am interested in your statement regarding the “inferior Amex rental car coverage”. What do you mean? i always thought it would be sufficient (but i never had an insurance case with a rental car). Can you explain that a bit and state better options? Thank you!
Use google. There are many pieces written that explain the difference in rental insurance coverage.
In particular, look for the phrase “primary coverage.”
If I’m reading this right, you need to make the reservation on the website, but payment can be at the rental facility as long as it’s before 5/31. So no need to prepay on the website. At least not the way I see it.
