2010 Lexus IS250 2.5L Petrol · DK10 GPF

The 2010 Lexus IS250 presents a mixed but broadly stable maintenance picture as of its most recent MOT on 11 August 2025 at 129,447 miles. That test passed, yet it followed a failure just five days earlier on 6 August 2025 at 129,434 miles, where a split nearside rear CV boot was flagged alongside corrosion advisories on the rear sub-frame and integral body structure. The rapid retest and pass suggest the CV boot was replaced promptly, which is encouraging. However, the same rear sub-frame corrosion advisory has persisted across both 2025 tests and appeared again in the August 2023 pass at 118,090 miles, indicating a long-standing surface corrosion issue that has not worsened to the point of structural concern but has not been addressed either. The overall trend is one of adequate but reactive maintenance rather than proactive renewal. The mileage progression tells a consistent story. Between the August 2023 test at 118,090 miles and the August 2025 test at 129,447 miles, the car covered roughly 11,357 miles in two years, averaging around 5,678 miles annually. That is lower than the lifetime average of approximately 8,090 miles per year, suggesting the car has seen lighter recent use or possibly spent extended periods stationary. The gap between the November 2022 test at 115,370 miles and August 2023 at 118,090 miles shows only 2,720 miles in nine months, reinforcing the impression of reduced activity. No mileage anomalies or rapid accumulation spikes are present in the record. A buyer should pay close attention to the rear sub-frame and surrounding structural corrosion, which has been flagged repeatedly since at least 2023. While testers have consistently judged it not seriously weakened, corrosion in this area can progress, particularly on a vehicle of this age. The front suspension arm bushes were noted as worn in August 2023, and with no subsequent advisory it is unclear whether they were replaced or simply not yet degraded enough to warrant a flag. Front tyres were close to the legal limit in August 2024, and rear brake pads were wearing thin in August 2023, so a physical inspection of current tyre tread depth, brake pad thickness, and any uneven wear patterns is advisable. The headlamp lens condition advisories from 2025 are minor but worth verifying for any deterioration in light output, particularly if the car is used frequently at night.
