Lexus Gs300: MOT pass rate and reliability data

The Lexus Gs300 passes its MOT first time more often than the average UK car, by 0.7 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 2,602 individual Lexus Gs300 tests. Nothing here is an estimate or a survey.

The numbers

What this means if you are buying one

A 77.4% first-time pass rate means roughly 23 in every 100 Lexus Gs300s presented for MOT fail on the first attempt. That is better than average, so a well-kept example is a reasonably safe used buy. The average Lexus Gs300 tested had covered 113,639 miles and was built around 2004.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. The Lexus Gs300 sits 0.7 points above the national average, ranked 1,538 of 2,005 models. On one bought as repairable salvage, the mechanical side is less likely to spring surprises, so your repair estimate should hold up reasonably well.

Before you bid: run the lot through the analyzer, check the car's own record, check the mileage, decode the VIN, and if it carries a marker use the write-off value calculator. Or compare it against another model.

Looking at a specific Lexus Gs300 rather than the model in general? The free check covers its MOT and mileage history, and the full HPI report confirms the insurance write-off category, outstanding finance and whether it is recorded stolen, from licensed data for 5 credits. Already own one that has been damaged? Work out whether fixing it beats selling it with the repair or scrap calculator, and see recorded closing bids for damaged Lexus Gs300s at UK salvage auction.

7. Parking brake efficiency below minimum requirement, 2.4% of tests (1.83x the national rate for this defect)
8. The strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired, 1.7% of tests (1.75x the national rate for this defect)
9. A headlamp or light source missing, inoperative or more than ½ not functioning in the case of LED, 1.7% of tests (1.41x the national rate for this defect)

From 2,605 DVSA-tracked Lexus Gs300 tests, 2024. DVSA testers marked 4.38% of these flagged Lexus Gs300 defects as "dangerous", meaning the tester judged the car unsafe to drive away, against 5.11% nationally.

Most common MOT advisories on a Lexus Gs300

An advisory doesn't fail the car - the tester flags it as worth watching, but it still passes. A different list from the failures above: what testers are noting on a Lexus Gs300 before it actually fails on it.

1. Product on the lens or light source which obviously reduces light intensity or changes emitted colour to other than white or yellow, 7.3% of tests (6.63x the national rate for this advisory)
2. The strength or continuity of the load bearing structure within 30cm of any sub-frame, spring or suspension component mounting (a 'prescribed area') is significantly reduced or inadequately repaired, 5.5% of tests (3.59x the national rate for this advisory), also fails
3. Exhaust system leaking or insecure, 9.7% of tests (3.4x the national rate for this advisory), also fails
4. Vehicle structure corroded to the extent that the rigidity of the assembly is seriously reduced, 3.8% of tests (3.02x the national rate for this advisory)
5. A shock absorber damaged to the extent that it does not function or showing signs of severe leakage, 11% of tests (2.82x the national rate for this advisory), also fails
6. A suspension component excessively damaged or corroded, 12.2% of tests (2.35x the national rate for this advisory)
7. Fluid leaking excessively and likely to harm the environment or to pose a safety risk to other road users, 10.4% of tests (1.86x the national rate for this advisory)
8. Number plate inscription missing or illegible, 4.1% of tests (1.56x the national rate for this advisory)
9. A suspension pin, bush or joint excessively worn, 16.9% of tests (1.26x the national rate for this advisory)
10. Brake pipe damaged or excessively corroded, 7.6% of tests (1.23x the national rate for this advisory)
