AUSTRALIA loves simple, highly literal naming conventions. Witness the Great Sandy Desert; the Sydney Harbour Bridge. To this, add Lang Lang Proving Ground. All you need to know is contained within those two last words. This is a place where Holdens are pounded until their mechanical integrity and their fitness for purpose is proven. For our application, itís where the COTY field is delivered its first round of punishment; the weeding-out process that sorts the greats from the merely good. Itís where the proving ground really does become the culling field.
