Also the 75 points for booking through the app, as widely reported here, works on a one day rental.
So you can get 375 1-2-F points for a single one day rental if you add the XM.
I did a one day rental with XM and got the 300 points. Initial car I picked up didn't have XM, was told at checkout they will waive the fees for XM. But didn't want to risk it for the points. So I went back and picked up another car with XM at PHL. Got all the points for a free day.
