2003 Lexus RX300 3.0L Petrol · BX53 ACZ

The vehicle presented for evaluation most recently passed its MOT test on 2 October 2025 with no defects or advisories recorded, continuing an unbroken run of pass results across the most recent four examinations. Looking at the broader DVSA history, the 2022 test introduced advisories concerning rear brake disc condition and front suspension arm pin or bush wear, while the 2021 test flagged similar lower suspension arm pin or bush wear. The fact that the 2023, 2024, and 2025 tests returned completely clean results suggests either that the previously noted suspension components remained within acceptable tolerances on re-examination or that remedial work was carried out in the intervening period. Overall, the maintenance trend appears stable and arguably improving, as no new advisories have emerged over the past three test cycles, indicating consistent mechanical upkeep or genuinely slow wear progression on the items previously highlighted. With a recorded mileage of 126,108 miles spread across approximately 23 years of service, this Lexus has averaged around 5,483 miles annually, which is notably low for a vehicle of its age. This pattern of usage typically reflects either a secondary or leisure vehicle status, or extended periods of standing between drives, both of which carry their own mechanical considerations. While low annual mileage reduces wear on major drivetrain components such as the engine, transmission, and clutch, prolonged standing can accelerate deterioration of rubber and protective finishes, promote corrosion on brake discs and calipers, and allow moisture accumulation in differentials and transfer units. The relatively even distribution of mileage implied by the consistent MOT testing pattern suggests the vehicle has been used regularly enough to avoid complete dormancy, which is a positive indicator. Given the clean MOT history of the past three years and the absence of recurring advisories, a prospective buyer should still conduct a thorough physical inspection attuned to the vehicle's age and modest usage profile. The tyres should be examined carefully for sidewall cracking, perishing, or uneven tread wear associated with age rather than mileage, as rubber compounds degrade with calendar years regardless of wear depth. The brake discs, particularly those noted as pitted in 2022, should be inspected for corrosion and the calipers checked for any signs of binding, which commonly develops on vehicles used infrequently. A test drive should include firm brake applications from higher speeds to confirm straight-line stopping without pulling or shudder, and low-speed manoeuvring should be performed with the windows down to listen for any suspension clonks or knocking that might indicate worn bushes or top mounts that have deteriorated since the last MOT. Additionally, listen for any transmission whine or hesitation, as automatic gearboxes in low-mileage vehicles can develop issues when fluid has not been refreshed according to time-based service intervals. Beyond the mechanical inspection points directly related to the MOT record, several age-appropriate service items warrant verification before purchase. The 12V battery should be load-tested, as units over five years old frequently fail without warning, particularly in vehicles with irregular use patterns. All fluid services, including engine oil, transmission fluid, coolant, brake fluid, and power steering fluid, should be confirmed as recently renewed, as these degrade with time irrespective of mileage and a 23-year-old vehicle will almost certainly have required multiple changes of each. The exhaust system should be raised on a ramp and inspected for corrosion at the mounting points, joints, and silencer, as age-related exhaust failure is common. Service history documentation should be cross-referenced with the mileage to verify regular attention, and any evidence of timing belt replacement, a critical interval service on this age of Lexus, should be specifically confirmed. With diligent inspection in these areas and a careful test drive, this clean-history, low-mileage example represents a reasonably maintained candidate worthy of serious consideration.
