IT WILL take a keen eye to spot the exterior changes to the lower-grade Commodores with the VXII upgrade, the most obvious being new paint colours (five in all), revised grille treatment and new wheel covers. Most improvements have centred on the interior or under the skin. New stalks for indicator, wiper and (when specified) cruise control functions are provided, the latter using a more intuitive twist switch mechanism instead of the previous button system. The cloth trim is now a micro-check pattern on the head restraints and seat bolsters. An alarm is also now fitted standard. The most significant mechanical change is the inclusion of the "control link" rear suspension, which features extra toe-control link arms for better rear-end stability.
