2008 Vauxhall Vectra 1.8L Petrol · AC08 WPA

The 1.8-litre petrol Vectra returns roughly 32–38 mpg in mixed driving, depending on whether it is the manual or automatic, which works out at around £1,500–£1,800 in fuel per year for a typical 8,000-mile driver at current pump prices. Road tax sits in band G for the post-2006 1.8, costing £210 per year as a petrol vehicle — a notable annual outlay for a car in this price bracket. Insurance is a genuine strength of the model, with the 1.8 Vectra typically falling into group 7 or 8, making it one of the cheaper large family saloons to cover.

Routine maintenance is inexpensive because parts are shared across the Vauxhall range and most independent garages are familiar with the car. A yearly service including oil, filter and plugs should come in at £150–£220, and front brake pads and discs are around £180 fitted. The biggest single cost to plan for is a cambelt replacement at roughly £350–£500 if it is overdue. Overall, expect annual running costs of £1,400–£1,800 once fuel, tax, insurance and maintenance are combined — competitive for the size of car on offer, but bear in mind that age-related repairs tend to rise sharply once a car passes 15 years old.

Despite the clean MOT sheet, several areas deserve close physical inspection. The aggregate Vectra failure data highlights tyres, brake pipes and washer inadequacies as the top reasons cars of this model fail — none of which appeared on this car's history, but all of which can reappear within months on a car of this age. Check all four tyres for legal tread (minimum 1.6mm but 3mm is wise), look for uneven rear brake wear which points to a sticking handbrake mechanism, and inspect the brake pipes under the car for surface corrosion, particularly along the fuel tank area. The washer system should be tested on both front and rear, as blocked jets are common.

On the 1.8 petrol engine specifically, listen at cold start for a rattle that disappears after a few seconds — this can indicate a worn timing chain tensioner, a known issue on higher-mileage examples. Check the oil filler cap for mayonnaise-like residue, which would suggest head gasket concerns, and pull the dipstick to confirm the oil level and that it is not excessively dark. Inspect the exhaust for blowing joints, as the rear silencer on the saloon variant frequently rots out well before the rest of the system. Finally, examine the front suspension for worn wishbone bushes, which is the single most common Vectra repair and should be budgeted for if any clonking is heard over speed bumps.
