So a Sixt rep confirmed to me today there are two types of Platinum member. One who gets single category upgrades and one who gets diddly squat.

To be frank, I couldn't believe it, but he was deadly serious. He said the change was made a year ago. Is this news to only me?

Only in the US does Sixt have any fleet advantage but even I have perceived this as eroding fast. I don't like to get a "50 cent car" from Hertz as an upgrade.

Mrs Sixt has really lost the plot. Most of the time in Europe I can book a M or G category at Hertz for much cheaper than Sixt. And there was post about a US station manager being told to flout local laws .
