Thought I'd give this thread a bump.
I'm tempted by the "Hertz Mystery Vehicle - Manual or similar" with a car type as in the title for $45/day in Australia when a Economy (Yaris) is $.50 less and a Compact (Corolla) is $1.50 more. The Mystery car description says " 1 Large Suitcase, 2 Small Suitcases" which seems like it might rule out Yaris or Corolla (who both have descriptions of " 1 Large Suitcase, 1 Small Suitcase").

About the only thing I'd be disappointed/mad to get would be a Yaris. I'm fine with it being a manual, but none of the other choices at the location are manuals. Has anyone done these in Australia? I've seen the American "manager's special" thread.
