2000 Lexus LS400 4.0L Petrol · K20 RCF

The Lexus LS400 has demonstrated a stable but not exemplary roadworthiness trend over the past five years, with the most recent MOT test on 26 January 2026 confirming no defects at 197,162 miles. While the vehicle passed without fail since 2022, the 2024 and 2023 tests revealed recurring issues: the steering rack inner joint exhibited persistent wear, the rear sub-frame and inner sills showed progressive corrosion, and the rear brakes were flagged for wear in 2023. The absence of major advisories or failures in the latest test suggests these problems have either been addressed or are currently tolerable, but the pattern indicates deferred maintenance rather than proactive care. The supplementary restraint system warning lamp issue in 2024—now resolved—was a critical oversight that should prompt verification of airbag system functionality. Mileage accumulation has been steady but not aggressive, averaging around 7,583 miles annually, which aligns with expectations for a vehicle of this age. The largest gap between tests occurred between January 2022 and January 2023, where mileage increased by only 6,158 miles over 12 months, suggesting periods of inactivity. Conversely, the jump from 186,077 to 187,709 miles between January 2023 and January 2024 (1,632 miles) was modest, indicating no sudden heavy usage. The lack of pre-MOT servicing records means this mileage data is the sole indicator of wear, but it does not preclude hidden issues like fluid leaks or internal drivetrain degradation. A buyer should prioritise an immediate inspection of the steering rack for excessive play or fluid leakage, as the inner joint wear has been a recurring issue. The rear sub-frame and inner sills require thorough examination for corrosion penetration, particularly around welds and mounting points, to confirm structural integrity. Rear brake discs and calipers should be checked for uneven wear or scoring, while the ABS and supplementary restraint system should be tested for proper functionality. Given the windscreen damage noted in 2025, visibility through all lanes should be verified, and any chips or cracks could indicate a history of poor protection from road debris. Engine bay components, including belts, hoses, and fluid levels, warrant scrutiny, as their condition cannot be inferred from the MOT history alone.
