A Vauxhall Vectra C (2002 to 2008) with the 1.8 petrol is the lower-risk buy, while a 1.9 CDTi diesel isn't worth having without receipts showing its timing belt and water pump were replaced together.
3 known faults, 3 rated high severity in our database; owners report 41.9 mpg, 93% of the official figure. Everything below is built from that data and the archived owner history, not from a press car.

Check a Vauxhall Vectra advert (free) →Go for a Vectra C (2002 to 2008) with the 1.8 petrol, because both High-rated known faults on the Vectra C sit on the 1.9 CDTi diesel instead. Don't read that as a clean record, though: there's very little on file about the 1.8 either way, so it's the lesser risk rather than a proven one, and its gearbox and clutch still need a proper test.
The 1.9 CDTi is the Vectra to be careful with. Its timing belt can be thrown when the water pump it drives seizes, which wrecks the engine, and the swirl flaps in its inlet manifold can break off and get sucked in. A diesel that's had its belt, water pump, tensioner and pulleys changed as one job, with the receipt to show for it, is the only 1.9 CDTi worth looking at.
The older Vectra B (1995 to 2002) is a harder sell. The 2.2 petrol from that era has a known timing chain fault, and the other engines have a long list of niggles from sensors to fuel pipes. If you're set on a Vectra B, pick a petrol other than the 2.2 and favour one with oil changed often, because cars left on long fleet oil intervals come out worse.
The 1.9 CDTi diesel is the engine to avoid unless the history's spotless, as it carries both High-rated faults on Vectra Cs built from 2004. A seized water pump can throw its timing belt between 40,000 and 60,000 miles, and fitting a new belt without a new pump can wear the old pump's bearing out quickly. On the Z19DTH version, the swirl flaps can snap and get swallowed by the engine between 60,000 and 100,000 miles.
On the Vectra B, skip the 2.2 petrol (Z22SE). An undersized oil spray nozzle can block and starve its timing chain of oil, bringing a rattle at start-up or idle, a warning light and misfires, usually between 60,000 and 100,000 miles. The 2.2 petrol's ignition control unit has a habit of burning out as well, and the Vectra C's 2.2 direct injection petrols have had high-pressure fuel pump and pressure sensor failures.
That leaves the 1.8 petrol as the one to have, since no known fault names it, although that's thin evidence rather than a clean bill. The other diesels aren't trouble free either: the 2.0 and 2.2 DI engines have been caught using oil because their bores were finished too smooth, and one owner's 3.0 V6 CDTi seized its camshaft after a service.
Gearboxes matter too. On diesels, the older F18 gearbox has failed and the later F23 followed it. Diesel automatics can be wrecked when the fluid cooler inside the radiator cracks and lets coolant into the transmission, which has turned up more than once, and the 6-speed auto had an internal overflow pipe cut too short, so it was underfilled, shifted jerkily and then failed.
Paperwork comes first. On a 1.9 CDTi, you want a receipt showing the water pump, tensioner and pulleys were changed along with the timing belt, and on an early 2.2 petrol, proof the timing chain oil feed has been dealt with. A 2001 ex-fleet car that lived on 20,000 mile oil changes is a weaker buy than one that had fresh oil at 7,000 miles or 6 months at most, and a Vectra from a fleet could have been clocked, so match the mileage to the history.
On the drive, a 1.9 CDTi that smokes, hesitates while cruising or drops into limp mode is showing the signs of seized swirl flaps or a sooted EGR valve. Listen for a rattle at start-up on a 2.2 petrol and metallic noises from the engine bay on a 1.9 CDTi. Make sure the clutch pedal springs back properly, as a weak return spring can contribute to a burnt-out clutch, and ask whether a 2007 car has had its dual-mass flywheel and clutch done.
Look behind the wheels for snapped coil springs, which fail often on the Vectra C, and don't ignore a creak from the front, which has turned out to be loose radiator mounts. On a Vectra B, check for rust round the rear door latches, try every window and see that the ABS light comes on and then goes out. On a Vectra C, test the tailgate switch, the wipers, the handbrake and the air conditioning.

Only buy one of these with a history showing frequent oil changes, and skip the 2.2 petrol, because a blocked spray nozzle can starve its timing chain of oil between 60,000 and 100,000 miles. The spring 1999 facelift made real improvements, though even then it didn't fully cure the heavy understeer of the first cars, so a later one's the better drive.
On the four-cylinder 16-valve engines with a timing belt, that belt also turns the water pump, and if that pump sheds the blades off its impeller, it can seize and throw the belt. The tensioner bolt, which runs through the oil pump, has been known to snap and leave the belt slack. Ask for receipts showing the pump's been renewed alongside a belt, not just the belt itself.
The 2.0 DI diesel has needed a new mass airflow sensor roughly every 36,000 miles, and poor starting on it has been traced to perished leak-off pipes on the injectors. Hard starting on a 2.0 DTI parked facing uphill overnight comes from worn O-rings in the fuel filter couplings. A 1.6, 1.8 or 2.0 petrol that idles at 1200 to 2000 rpm needs its idle air control valve cleaned or swapped.
Power steering pumps and front discs have both needed replacing at around 35,000 miles, air conditioning compressors fail repeatedly, and the front suspension can wear early. Estates can rattle from the roof stiffeners, and a steering column rattle's another one to listen for. V6 cars were recalled in June 2000 for a crankshaft fault, so ask for proof that work was done.

Yes, with the 1.8 petrol, but pass on a 1.9 CDTi unless the belt and water pump paperwork is there, because that pairing causes the Vectra C's most serious known fault. The belt failures, recorded on cars from 2004, show up between 40,000 and 60,000 miles, and one owner's 2007 1.9 CDTi had its camshaft belt pulley collapse a year after a new belt went on.
Beyond the belt, the 1.9 CDTi's Z19DTH version has swirl flaps that seize or break between 60,000 and 100,000 miles, and the proper fix is a new inlet manifold. EGR valves soot up, DPFs choke and turbos have failed too. Its wiring harness can rub through on the gearbox casing, which blows the main fuse and leaves the car unable to go anywhere at all.
The DI diesels have their own list: EGR valve trouble can put them into limp mode, and air getting in past the injector seals on the 2.2 DI causes poor starting and cutting out. On the 2.2 diesel, the dual-mass crankshaft pulleys for the timing chain can fail. One owner's 2007 2.8 VXR destroyed its engine when the timing chain let go.
Across the range, coil spring failures come up again and again, and one owner's 2008 car had both rear springs replaced free after an MOT found one broken. A 2004 recall fixed a rear exhaust pipe that could slide off the front section, and a 2005 recall covered rear axle hubs that weren't built to spec. One owner paid £151.72 when the driver's door lock fell apart.

Vauxhall Vectra Real MPG by engine →It's a comfortable car for covering ground: the ride's smooth, and it's at its best on the motorway. The Vectra C has a lot more room inside than the car it replaced, so it feels bigger than you'd expect from the outside, and the headlights always come back on dipped when you switch them on, even if you'd left them on main beam.
The right one can go a very long way. One owner's 2008 1.8 petrol passed 250,000 miles on the engine, gearbox, clutch and exhaust it left the factory with, and it needed very few repairs along the way. That's one car rather than a rule, but it's a good sign for the petrol that's the safer pick in this range.
