This IS the Crown Casino coke competition car.

The car is based at Ardrossan in SA, and the owner is likely selling at this price because of what the Coke promoters told them the value. Therefore there is no rush for this person to sell because they won it for what maybe a lucky bottle of soft drink.

If you wanted the car, I would suggest giving them a call and making a more reasonable offer because whatever they get, it is more than what they paid for it.
