Thule Xtender 6 ski Holder with Roof Racks and fitting for 2008 Audi A3.
I believe that this will also fit many other cars in the Audi Range which have solid rails.
Costs over $500 new. The Xtender ski carrier is $399 alone. Only selling due to change of car (and got dealer to throw new racks in).
Available to inspect during business hours at Surrey Hills or Rosanna after hours.
