2004 Lexus IS200 2.0L Petrol · AV04 FUG

A discernible pattern of structural and chassis corrosion sits at the heart of this Lexus IS200's MOT record, even though every test has been passed without failure. The narrative begins to emerge in 2022 with advisories noting slight corrosion on both outer sills, then evolves through clean passes in 2023 and 2024, before culminating in the most recent test on 23 March 2026 which recorded corroded rear suspension components along with a repaired section of vehicle structure deemed not to have significantly reduced rigidity. While none of these entries constitute a failure, the progression from cosmetic sill corrosion to component-level corrosion on the suspension indicates that the chassis area is actively deteriorating rather than holding stable. The presence of a previously repaired structural section also warrants particular scrutiny, as it is essential to confirm the quality and integrity of that prior repair. Against a 22-year service life, 145,322 recorded miles equates to approximately 6,600 miles per year, which broadly aligns with average usage expectations for a vehicle of this vintage. The MOT records are evenly spaced at roughly annual intervals from 2022 onwards, indicating the car has been in continuous road use and has not been laid up for any extended period where corrosion could advance unchecked or fluids could stagnate. This continuity is mechanically reassuring, as it suggests the drivetrain, seals, and ancillary components have been kept active, though the higher overall mileage does place greater cumulative demand on suspension bushes, engine gaskets, and braking components. For a prospective buyer, the rear suspension corrosion advisory from March 2026 is the primary area of concern and demands a close physical inspection of the rear beam, trailing arms, coil springs, and any associated mounting brackets for advanced surface scaling or section loss. Listen for clonking or rattling noises from the rear axle over uneven surfaces, particularly on speed humps and broken tarmac, as corroded bush housings and spring seats typically generate audible slack before they become visible to a casual glance. The repaired structural section should also be examined closely to ensure there is no fresh cracking around the repair boundary, no differential panel thickness, and no evidence of flexing under load, ideally with the vehicle raised on a ramp for a proper underside view. The front oil leak noted in March 2025, while not excessive, should be investigated by checking for oil residue around the cam cover gasket, sump, and power steering pump area, with attention to any fresh staining on the undertray or driveway surfaces. The sills themselves, first flagged in 2022, are another inspection priority. Slight corrosion on a 2004 vehicle can progress quickly once initiated, particularly on a model of this age exposed to winter road salt, so the outer sills, jacking points, and inner wheel arch lips should be probed or tapped to check for paper-thin metal or bubbling beneath the surface paint. On the test drive, pay attention to any steering vagueness, uneven braking response, or pulling to one side, as compromised rear suspension geometry caused by corroded components can manifest as reduced directional stability. Finally, while the minor windscreen damage recorded at the last test was not deemed to obstruct the driver's view, it is worth ensuring that any chips or cracks have not propagated since, and that all general service items such as coolant, brake fluid, and timing belt replacement history are verified given the high mileage and the car's advancing age.
