1989 Fiat X1/9 — MOT failures & pass rate
294 MOT tests on the 1989 Fiat X1/9 are in this dataset, and 81.3% of them passed. That is 2.6 percentage points better than all cars of a similar age, which fail at 21.3%. Failures cluster in lighting & signalling, brakes and visibility.
What the MOT record shows
One area stands out: lighting & signalling, recorded in 12.6% of tests against 9.2% for the next-worst category.
At component level the recurring items are headlamp, service brake performance and headlamp aim — headlamp alone was recorded 24 times.
Suspension is the most common advisory, noted on 14.3% of tests — work that passed today but is likely due soon.

|---|---|---|
| 30-60k | 138 | 12.3% |
| 60-90k | 99 | 23.2% |
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 1989 X1/9
The failure pattern for this year is specific enough to inspect against: lighting & signalling accounted for 12.6% of tests. Start there.
- Lighting & signalling (12.6% of tests): Often a cheap bulb, but persistent issues can mean wiring or corrosion in the units. Typical repair: £10–£150.
- Brakes (9.2% 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.
- Visibility (6.5% of tests): Wipers, washers, mirrors and screen damage — usually inexpensive, but check for chips in the driver's line of sight. Typical repair: £15–£150.
Repair costs are rough UK ballpark ranges to set expectations, not quotes — actual prices vary widely by car, parts and garage.
