1998 Lexus LS400 4.0L Petrol · R41 OVN

Corrosion on the underbody and suspension components represents the primary long-term mechanical risk for this vehicle, as flagged in the October 2024 advisory. While the most recent test on 24 September 2025 resulted in a pass with no recorded defects, the previous year's inspection highlighted structural and component-level oxidation that warrants close scrutiny. The vehicle's history shows a generally stable pattern of roadworthiness, though the 2022 failure due to a fractured nearside rear coil spring indicates that suspension components are subject to fatigue or environmental degradation. The recorded mileage of 133,831 miles over approximately 28 years equates to an average annual accumulation of roughly 4,780 miles. This represents a low-use profile for a vehicle of this age. Mechanically, such low annual mileage can mean that while drivetrain components may have lower cumulative wear, other elements like rubber suspension bushes, seals, and various rubber hoses may have undergone more significant age-related perishing due to extended periods of inactivity or limited thermal cycling. A prospective buyer should pay particular attention to the underbody during a physical inspection, specifically looking for the extent of the corrosion mentioned in the 2024 advisory. Focus on the condition of the subframe, brake pipes, and suspension mounting points. On a test drive, listen for any rhythmic knocking or clunking sounds when traversing uneven surfaces, which could indicate perished or loose suspension bushes or failing dampers. Given the previous failure of a coil spring, any unusual bouncing or a vehicle feeling unsettled through corners should be treated as a sign of further suspension component fatigue. The advisories regarding thin front and rear brake pads from late 2024 should also be verified. Although no defects were noted in the 2025 test, the wear recorded previously suggests the braking system is approaching a maintenance interval. During the test drive, monitor the brake pedal for any excessive travel, sponginess, or vibration through the pedal face, which could indicate worn discs or issues with the hydraulic system. Ensure that the braking performance is consistent and that there is no audible squealing or grinding during deceleration.
