The last generation of the Vauxhall Vectra Estate (station-wagon) was introduced in 2003, two years after the introduction of the rest of the range.
It was refreshed, along with the entire range, in 2005.

The Vectra C used the same platform with the Saab 93 and other GM products on both sides of the Atlantic. It was used for Holden in Australia as well. The Vauxhall Vectra Estate was the British version of the European Opel Vectra Station-wagon.

The facelifted version featured a completely new front end design, with swept headlights and a bigger chromed Vauxhall-bar on the grille. In the rear, there were slightly modified taillights and bumper.

Depending on the trim level, the interior could feature cloth or leather seats, a simple CD-Radio, or an infotainment unit with a navigation system. The front seats featured slight bolsters, built more for comfort rather than for high-speed cornering. After all, the Vectra station-wagon was a family car. In the back, there was room for three adult passengers on the bench. The trunk could have been extended by folding the backseat in a split, 60/40 way. That led to an increase in trunk space of up to 1850 liters (65.3 cu-ft).

After the facelift, the Vectra range received a new range of engines, according to Euro 4 pollution norms. It took a 1.9-liter diesel engine from Fiat. The 3.0-liter diesel from Isuzu was improved and received more power.
