I need to book a rental car for a trip to Germany soon but I'm not sure which card I should put it on. I haven't received my Sapphire card yet but I have been approved. I need to meet a spend limit on this card anyways so I'm thinking I'd prefer to put it on that one.

However - I also know that the Continental card is one of the only cards with primary car rental insurance. Can't find any documentation on how the Sapphire protection stacks up...

Any thoughts?
