Here we go again. You may remember the story of Elvis Boustani and his Audi Q7.

On June 1, 2011, Elvis took delivery of what he thought was a new Audi from Wollongong's Southern Classic Cars. The paperwork, of which we have copies, shows the car was sold as a new car. Since early 2012, the engine has leaked more oil than three old Jaguars do in a day.

After we sent a number of emails to Audi's general manager corporate communications, Anna Burgdorf, she eventually confirmed the Q7 "was registered in the dealership's name approximately one month before Mr B purchased it, and was therefore technically a demonstration vehicle — although it was never driven."

Since 2012 the Audi has been back and forth to the dealer for oil leaks. Since January this year the car has been under the tender loving care of the Audi mechanics a total of five times. That makes a total of 13 weeks the Q7 has been in hospital.
