1997 Lexus Gs300 — MOT failures & pass rate
456 MOT tests on the 1997 Lexus Gs300 are in this dataset, and 82.2% of them passed. That is 7.4 percentage points better than all cars of a similar age, which fail at 25.2%. Failures cluster in suspension, brakes and lighting & signalling.
What the MOT record shows
No single area dominates — suspension (8.3%) and brakes (7.7%) are close, so failures are spread across several systems rather than one weak point.
At component level the recurring items are service brake performance, wipers and component mounting prescribed areas — service brake performance alone was recorded 23 times.
Mileage is the strongest signal on the record: 14.6% of 60-90k cars fail, rising to 24.8% once past 150k.
Suspension is the most common advisory, noted on 35.5% of tests — work that passed today but is likely due soon.

Top advisory categories
Advisories aren't failures, but they flag work likely needed soon — useful when budgeting.
| # | Category | % of tests with advisory | Tests |
|---|---|---|---|
| 1 | Suspension | 35.5% | 162 |
| 2 | Brakes | 29.4% | 134 |

| 60-90k | 82 | 14.6% |
| 90-120k | 83 | 19.3% |
| 120-150k | 130 | 13.1% |
| 150k+ | 141 | 24.8% |
Failure rate by age
Trend over time
| Dataset year | Tests | Fail rate |

What to check before buying a 1997 Gs300
The failure pattern for this year is specific enough to inspect against: suspension accounted for 8.3% of tests. Start there.
- Suspension (8.3% 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 (7.7% 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 (7.2% 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.
