Another Hertz Australia prestige update - it seems like all the models are now the 2017-18 models - the last of the B8 Q5/SQ5's are gone. Lots of them now at Pickles
All the Q2s seem to be the base model TFSI, and the Q5s the base TDI with no sunroof, active cruise control etc.
The A4's are the petrol version, but some of them now do have the sunroof and the Audi Virtual Cockpit installed. None of those have active cruise control still, sadly. Some of the Q7's also appear to have Audi VC, but haven't had a chance to rent one yet.
