Holden themselves even blatantly pushed the Evoke as the fleet choice.
With VF, they took the VF more towards the aspirational purchase and less "everyman" car, hence the most popular model being V6 SV6 then Calais, then onto the Halo SS models.
Not to say Evoke was bad! When they where designing VF, supposedly the head of GM design was visiting and was extremely impressed when he seen the full size clay and asked to see the fleet model, to which they responded that he was looking at the fleet model.
I think a good find is an Evoke international for an everyday car, given you then get a Calais interior and front DRL's which make it look much better . But generally, people who go an Evoke probably are not the type to be purchasing here. As a buyers market, I just couldn't justify the small price different between an Evoke/SV6, given you get a big jump in kit and interior
