The third generation of the Opel Vectra, known by the code "C", was launched in 2002, succeeding the Vectra B. Positioned in the family car segment, it was available as a 4-door sedan, 5-door hatchback (GTS), and station wagon (Caravan). It shared its Epsilon platform with other GM models like the Saab 9-3. A significant facelift took place in 2005, bringing aesthetic modifications (front fascia, lights) and technical improvements, notably the introduction of new diesel and petrol engines. The Vectra C was renowned for its comfort, generous interior space, and safe road handling, although sometimes considered a bit bland. Its reliability is mixed, with petrol engines generally decent but with some notable weaknesses, and diesels whose reputation varies greatly depending on the engine.
The Opel Vectra C is a spacious and comfortable family car, offering good value for money on the used market. However, its reliability is highly dependent on the chosen engine. The 1.8L petrol engines (especially the Z18XER) and V6s (3.2L and 2.8T) are the most recommendable for their driving pleasure and decent reliability, provided they are regularly maintained. The 1.9 CDTI diesels are a reasonable choice, but beware of swirl flaps and DPF on the 150hp version. It is strongly advised to avoid the 2.0 DTI, 2.2 DTI (due to the VP44 pump) and 2.2 Direct (Z22YH) engines due to major and costly problems. For the others, a thorough inspection of the service history and an in-depth test drive are essential. It can be an excellent purchase if you choose the right engine and a well-maintained example, but can quickly become a money pit otherwise.
