2005 Alfa Romeo Gt — MOT failures & pass rate
The 2005 Alfa Romeo Gt passed 69.6% of its 1,739 recorded MOT tests. All cars of a similar age fail 27.6% of the time, so this is 2.8pp worse than the group it competes with. Failures cluster in lighting & signalling, suspension and body, structure & corrosion.
What the MOT record shows
No single area dominates — lighting & signalling (15.9%) and suspension (14.2%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are headlamp aim, component mounting prescribed areas and washers — headlamp aim alone was recorded 179 times.
Condition tracks the odometer closely. Failures run at 21.8% in the 30-60k band and 36.5% in the 150k+ band, a 14.7-point spread.
Split by fuel, diesel examples fail 11.7pp more often than petrol ones (36.6% vs 24.9%) — worth weighing if you have a choice.
Advisories point at the next bill rather than this one: suspension was flagged on 35.5% of tests without failing them.
The trend is improving — the fail rate fell from 33.5% in 2021 to 30.4% in 2025, as the worst-kept examples leave the fleet.

What to check before buying a 2005 Gt
On a 2005 Gt, lighting & signalling is what the MOT record says goes wrong most — it appeared in 15.9% of tests. Check these areas before you commit.
- Lighting & signalling (15.9% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Suspension (14.2% 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.
- Body, structure & corrosion (10.3% of tests): The one to take seriously on older cars — corrosion to structural areas can be costly and is an MOT failure. Typical repair: £200–£1,500+.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
