Should I check the MOT history before buying a 2006 London Taxis Int Tx4?

Moderate sample. 378 vehicles on record. Figures are indicative — the specific vehicle's history matters more than these averages.

The TX4's 73.4% first-time pass rate sits noticeably below the UK average of 80%, signalling reliability challenges—but the real concern is that 44.7% of these vehicles have recorded dangerous defects, well above acceptable levels and a significant buyer warning sign. Nearly all TX4s are diesel, so the fuel type isn't a differentiator here.

These taxis have covered serious mileage (median 240,526 miles), which partly explains the strain, but the average of 5.27 failures and 17.4 advisories per test reveal chronic wear across multiple systems rather than isolated issues. If you're considering a TX4, budget for a full pre-purchase inspection focusing on braking, steering, and suspension—don't rely on the MOT pass alone to tell you the vehicle is safe.

The 2006 London Taxis Int Tx4 has a below-average first-time pass rate (73.4% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.

⚠️ 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

⚠️ Below average. More vehicles in this cohort fail their first MOT than typical. Scrutinise this vehicle's history — look for recurring issues, not just the latest result.

🔧 Expect consumable spend. An average of 17.4 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 378 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.
