2004 Lexus RX300 3.0L Petrol · KB04 LDB

The vehicle currently holds a valid MOT certificate, having passed on 21 March 2026 with no defects or advisories recorded against it. This is a positive indicator of its present roadworthy condition, particularly when considered alongside the consistent pass results over recent test cycles in March 2025 and April 2024. It is worth noting, however, that the most recent pass was achieved only two days after a prior test on 19 March 2026 was recorded as a failure; although no specific defect categories were captured in the data provided, this pattern suggests a minor rectification was carried out immediately prior to the retest. Such a sequence is not uncommon for vehicles of this age, but it does warrant a brief enquiry as to what remedial work was undertaken, in order to confirm the issue has been properly resolved rather than temporarily addressed for the purposes of the test. With a recorded mileage of 144,498 miles over approximately 22 years, this Lexus RX300 has averaged around 6,568 miles annually, which is broadly typical for a vehicle of its vintage and broadly consistent with predominantly domestic, lower-intensity use. This relatively modest annual figure suggests the engine, transmission and driveline have not been subjected to excessive high-mileage wear, but the age of the vehicle is the more pertinent factor for many components. Calendar-related degradation, rather than distance-related wear, is likely to be the dominant concern across rubber, polymer, and fluid-based systems. The mileage gaps between test entries appear unremarkable, and there is no evidence of unusually rapid accumulation that would suggest prolonged high-speed motorway use or heavy towing duty, though specific odometer readings between tests have not been disclosed in this dataset. Given the absence of recorded advisories or defect categories across the available MOT history, the buyer cannot rely on previous tester observations to flag likely upcoming maintenance. Instead, a thorough age-appropriate physical inspection becomes essential. Tyres should be examined closely for sidewall perishing and cracking, which is common on vehicles of this age even where tread depth remains adequate, and any tyres over six years old should be replaced regardless of remaining tread. The braking system warrants particular attention; given the vehicle's age and the likelihood of extended standing periods, the brake calipers may have developed corrosion or binding, which can manifest as pulling to one side under braking, uneven disc wear, or a spongy or dragging pedal feel. Discs should be inspected for lipping and surface corrosion, and the handbrake mechanism should be checked for full and balanced engagement. Beyond the obvious, several calendar-based service items should be verified regardless of the car's mileage. The 12-volt battery is likely nearing or beyond its typical service life, and a load test or simple voltage check under load is advisable to avoid premature failure. Engine coolant, automatic transmission fluid, brake fluid, and power steering fluid all degrade with time and moisture absorption; a comprehensive fluid condition assessment, ideally accompanied by service book evidence confirming periodic replacement, will indicate how well the vehicle has been preserved. The suspension components, including coil springs, anti-roll bar links, and bushes, should be examined for wear or cracking, as these parts commonly deteriorate through age rather than mileage. Finally, during any test drive, listen carefully for clonks from the front suspension over uneven surfaces, any hesitation or juddering from the automatic transmission, and ensure the climate control and all electrical systems operate correctly, as rectification costs on a vehicle of this pedigree can rise quickly once general wear items begin to compound.
