Nothing.
The SS wagon is great for the family that would like to have a sporty car.
Great acceleration and handles well.
The engine likes the open highway, but doesn't like going slow around town.
Bet its thirsty? (At least its not a SUV)
The VY ss Wagon is an awesome car. You see many replicas around, but the original ones are the real deal. I reckon it's the best wagon around. It has the looks, the power and it's very comfortable to drive.
