Holden dealers are not allowed to advertise brand new cars and most demos anywhere other than their own website. Holden actively blocks out cars and provides Carsales with a list of cars that are allowed to be listed. If a dealer gets caught, the punishment is hefty and they risk losing their dealership, so I don't think that it's in their best interests. Most manufacturers now operate under this system. If you do a search now for a 2016 Some like it hot Calais V Sedan anywhere in Australia only 4 generic listing comes up (2 V6 and 2 V8).
