Mr Corney loves driving his big 4WD which his kids call 'Gus'. With the lower price of diesel, he thinks that it is cheaper to run than his wife's car, a little shopping cart that your Nana would drive called 'Mitsi'. His wife is very cost conscious and insists that Mr Corney drive to school in 'Mitsi'. Mr Corney wants to 'prove' to his wife that it is cheaper to drive 'Gus'. Maybe it is even cheaper for him to go by bus?
