Mileage seems to be the same as whatever the AWD you use would normally be. Points seem to just reduce the time and mileage charges in the same way a gift card, coupon, or other instrument would, to the point of the taxes and fees not being reduced for days that are paid with points, with the caveat that you don't get 7 days for the price of 5 when renting weekly like you would when paying cash.

That, I find terribly annoying.
