Probably they were "sold out". Actually Sixt reduced their fleet in the last year to have a better utilisation of their cars. From what I understand they were/are quite successful with their strategy.

Those kind of updated couldn´t be expected even for Diamond-card holders.
Sure it was a M3?

I really had several phantastic upgrades with Sixt but never was handed out the M3.

PDMR (BMW 520d), opted for downgrade as I needed a BMW (they offered me a Lexus, but no time to read the manual) and they only charged the lower PDMR fee

Seems to me that you are likely to be upgraded (or receive a totally different car) when renting from smaller stations. The "best" I've ever received was a fully-featured MB E350 CGI with a Brunswick (!!) number plate, although I didn't really like the that car... Pity they don't have the Audi A6 3.0tdi any more.

Yep, it was a great upgrade. Once we saw that we got such a nice car, we decided to carry our road bikes with us on our holiday trip and it made the holiday even better :) ^ to Sixt :)
