The 2011 TX4 passes its first MOT attempt only 73.1% of the time, well below the UK average of 80%, and more than half of these vehicles (56.3%) have recorded a dangerous defect at some point—a significant concern for any prospective buyer. This is a working taxi that's been hard-used, and it shows.

At nearly 176,000 miles on average, these cabs have covered serious ground, yet they still rack up 7 failures and 20 advisories per test on average, pointing to systematic wear in brakes, suspension, and bodywork rather than isolated problems. If you're considering one, budget for repairs before purchase and factor in that this model demands more maintenance than the typical 13-year-old car to stay roadworthy.

The 2011 London Taxis Int Tx4 has a below-average first-time pass rate (73.1% 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.

🔍 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 1,256 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.
