amex centurion do not get sixt diamond. this is a myth. dont know who created it. it is definetly not true. amex centurion get double upgrade on the centurion rate if available. however they do not get a diamond card
and as well: amex plat do not get a sixt plat. (only possibility I know of is, that sixt amex gold may get a sixt plat... but even that I am not sure)
