To be honest Dunny, the fuel consumption isn't that bad on the V6. In fact, it was often better than my 1.8 Astra! It all depends on your driving style. If you like to plant your right foot in the carpet, it will be expensive, just like any other car.
The V6 engine is a smooth drive, with plenty of power when you want it, not to mention the exhaust note when you really give it the beans.
:'( I miss that car.
