A countdown timer on their website confirms that HSV have something special planned to celebrate this milestone.
Several members of the Australian LS1 community have speculated on the exact specifications of the anniversary edition.
"The exact specs on this 20th anniversary are not exactly clear. R8 & Sandstorm colour are a given, Interior is Onyx/Light urban not clear if this means two tone as with the red hot option or that the stiching colour is light urban, Rims are shadow chrome, fingers crossed they are same as GTS but I doubt it. Number of these being produced is 100 only."
