2008 Saab 9'3 — MOT failures & pass rate
42,767 MOT tests on the 2008 Saab 9'3 are in this dataset, and 74.9% of them passed. That is 2.7 percentage points worse than executive cars of a similar age, which fail at 22.4%. Failures cluster in suspension, brakes and lighting & signalling.
What the MOT record shows
One area stands out: suspension, recorded in 13.1% of tests against 8.3% for the next-worst category.
At component level the recurring items are coil spring, tread depth and headlamp aim — coil spring alone was recorded 3,345 times.
Condition tracks the odometer closely. Failures run at 11.7% in the 0-30k band and 27.6% in the 150k+ band, a 15.9-point spread — more than double.
The petrol cars hold up better: 22.4% fail against 26.4% for diesel, a 4.0-point gap across 42,754 tests.
Suspension is the most common advisory, noted on 27.4% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 26.2% in 2021 to 24.5% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2008 9'3
The failure pattern for this year is specific enough to inspect against: suspension accounted for 13.1% of tests. Start there.
- Suspension (13.1% of tests): Worn drop links, bushes, springs or shocks — listen for knocks over bumps and check for uneven tyre wear. Typical repair: £150–£450 per corner.
- Brakes (8.3% of tests): Pads/discs are routine wear; binding, imbalance or corroded pipes are more serious — test for pulling under braking. Typical repair: £100–£350 per axle.
- Lighting & signalling (7.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
