Should I check the MOT history before buying a 2005 Lexus Rx300?

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.

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 2005 Lexus RX300 posts a first-time pass rate of 81.6%, marginally better than the UK average of 80%, though the genuinely concerning figure here is that 39.5% of these vehicles have recorded a dangerous defect at some point—nearly double the typical rate—so structural or safety issues are a real buyer consideration. This is a nine-year-old car when tested, and the median mileage of 78,286 miles is reasonable for age, suggesting these vehicles have been looked after reasonably well.

The average of 3.18 failures per vehicle tells you most examples need some work to pass, while the very high advisory count of 22 per vehicle indicates widespread minor wear and tear, typical of an ageing premium SUV with complex systems. Get a pre-purchase inspection focused on suspension, steering components, and the hybrid-style power steering system before committing, as these consistently show up in the advisory data across the cohort.

The 2005 Lexus Rx300 has a decent first-time pass rate (81.6%), 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 22 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 2,840 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.
