2007 London Taxis INT TX4 2.5L Diesel · LC07 YAX

A remarkably clean MOT history defines this 2007 London Taxis International TX4, with the most recent test on 20 May 2024 passing without a single advisory or defect recorded. This pattern of consistent roadworthiness is particularly noteworthy for a vehicle of this vintage and operational type, as hackney carriage work typically subjects taxis to punishing urban duty cycles with frequent stop-start traffic, heavy kerbside loading, and constant low-speed manoeuvring. The intervening test on 24 May 2023 also passed cleanly, and although a failure was logged on 10 November 2023, the subsequent retest just five days later on 15 November 2023 passed without recorded defects, suggesting a minor rectification such as a bulb replacement, wiper blade, or category-specific rectification that was promptly addressed. Across all five recorded tests spanning late 2022 to mid 2024, no structural corrosion, brake pipe concerns, suspension component failures, or exhaust integrity issues have been flagged, indicating that the fundamental safety-critical elements have remained within MOT tolerance. The recorded mileage of 397,143 miles against a vehicle age of approximately 19 years equates to an annual accumulation of around 20,902 miles, which sits well above the average for a passenger car but is broadly consistent with the working life of a London taxi. This high-mileage profile carries direct mechanical implications: the engine, automatic transmission, clutch components, prop shaft, rear axle assemblies, and steering rack will have accrued substantial wear, and consumable items such as engine mounts, gearbox mounts, and driveshaft support bearings may be approaching or beyond their intended service life. The relatively short intervals between successive MOT entries in 2023 and 2024 indicate continuous operational use rather than extended periods of standing, which is mechanically favourable as it avoids the corrosion risks associated with dormant brake discs, perished rubber gaiters, and dried-out transmission seals. However, the density of usage means that wear-related failures on items not strictly examined during the MOT test, such as clutch slip, torque converter judder, or rear axle whine, would not appear in this record. For a prospective purchaser, the absence of recorded advisories is a positive baseline, but it warrants healthy scepticism given the mileage and the inherent demands placed on a TX4 chassis. On a test drive, particular attention should be paid to the rear suspension geometry, as London taxis are known for wear in the leaf spring mounting points, trailing arm bushes, and the transverse links; listen for clonking over uneven surfaces and check for uneven rear tyre wear which can indicate geometry drift. The braking system should be evaluated for any pulling to one side under firm pedal application, spongy pedal feel suggesting corroded rear brake pipes, or binding calipers that may cause uneven disc wear, particularly given the heavy kerbside loads these vehicles endure. Under the bonnet, inspect for evidence of oil misting from the cam cover gasket or rear main seal, check the coolant expansion tank for pressurisation indicating head gasket distress, and verify that the automatic transmission engages smoothly through all ranges without flare or harsh engagement. Finally, examine the underside of the vehicle on a ramp if possible, focusing on the front subframe and steering rack mounting points for any corrosion that may have developed but not yet reached the MOT failure threshold. The condition of the exhaust system, particularly the downpipe and rear silencer assemblies, should be inspected for blueing or blow holes, and the prop shaft universal joints checked for any rotational play. Given the absence of MOT advisories, there are no specific components flagged in the record to direct targeted inspection beyond standard high-mileage taxi concerns, but the sheer scale of accumulated mileage means that a comprehensive pre-purchase inspection by a specialist familiar with TX4 mechanicals would be strongly advisable to verify the condition of major drivetrain and chassis components that fall outside the scope of the standard MOT examination.
