Before you buy a Mazda 3, Corolla, Astra, Civic, Lancer look here
"We bet $250 that you won't buy one of those (Toyota Corolla, Mazda3, Holden Astra, Honda Civic or Mitsubishi Lancer) if you test drive one of these (Ford Focus) first"
I am not exactly sure, but it looks like if you buy any new Toyota Corolla, Mazda3, Holden Astra, Honda Civic or Mitsubishi Lancer vehicle between 19th October to 30th November and test drive a Ford Focus, you get $250. You may want to read the terms and conditions yourself to make sure.

You can't just test drive the Focus, but you also have to buy one of the alternative, which are all at least $20k+
Obviously you won't go and spend $20k+ in order to get $250 so it only applies to those who are determined in buying Corolla, Mazda3, Astra, Civic or Lancer.
