2006 Alfa Romeo Gt — MOT failures & pass rate
The 2006 Alfa Romeo Gt passed 67.1% of its 1,755 recorded MOT tests. That is 5.7 percentage points worse than all cars of a similar age, which fail at 27.2%. Failures cluster in lighting & signalling, suspension and brakes.
What the MOT record shows
No single area dominates — lighting & signalling (17.0%) and suspension (16.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are component mounting prescribed areas, pins and bushes and headlamp aim — component mounting prescribed areas alone was recorded 172 times.
Condition tracks the odometer closely. Failures run at 22.7% in the 30-60k band and 43.0% in the 150k+ band, a 20.3-point spread.
The petrol cars hold up better: 29.8% fail against 34.3% for diesel, a 4.5-point gap across 1,755 tests.
Suspension is the most common advisory, noted on 34.7% of tests — work that passed today but is likely due soon.
The trend is improving — the fail rate fell from 33.8% in 2021 to 26.6% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2006 Gt
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 17.0% of tests. Start there.
- Lighting & signalling (17.0% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (16.7% 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 (11.3% 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.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
