Should I check the MOT history before buying a 2006 Lexus Gs450h?

Yes. Look for recurring advisories — slow-building issues like corrosion or brake wear patterns show up years before they become failures. A full MOT history analysis will highlight patterns that a single test result won't reveal.

Check brake pipes, sills, subframes, and chassis legs. Surface rust is normal at this age; structural rust is a serious problem that is expensive to fix and can fail an MOT.

Tyres and brakes are the most common advisory items on vehicles of this age. Budget for replacement if they are near the limit, and factor this into your offer price.

The 2006 Lexus GS450H passes its MOT at 81.4%, marginally ahead of the UK average, but nearly 40% of these vehicles have experienced a dangerous defect at some point—a significant concern for any buyer considering one. The hybrid and electric variants show fractionally lower pass rates (80.1% and 81.7%) compared to petrol models (82.7%), suggesting the petrol engine is the more straightforward option mechanically.

At an average mileage of 86,439 miles for an 18-year-old car, these are well-used examples, and the high advisory count of 16.6 per vehicle reflects the wear you'd expect from age rather than exceptional fragility. Focus your pre-purchase inspection on the hybrid battery system (if choosing that variant) and request a full service history, since the average 3.17 failures per test indicate cumulative maintenance costs will be material for this generation.

The 2006 Lexus Gs450h has a decent first-time pass rate (81.4%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

🔧 Average reliability. Passes at roughly the UK rate — not a standout, not a problem vehicle. Individual history makes all the difference.

🔧 Expect consumable spend. An average of 16.6 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 501 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
