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% back or more at Sixt (I received such an offer in a couple of emails just today), up to as much as 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, with the offer savings in this case, it might be worth paying a little extra for coverage in order to get a good stack.
