1999 Lexus GS300 3.0L Petrol · S293 ABB

The most recent MOT inspection for this Lexus GS300 was passed on 23 June 2025, following a failure involving headlamp aim and a stop lamp. While the vehicle is currently compliant, the overall maintenance trend suggests a pattern of recurring minor electrical and lighting issues, alongside persistent structural concerns. Of particular note is the presence of long-standing advisories regarding corrosion, which have appeared consistently over several years. While the vehicle has managed to pass recent tests, the recurrence of specific defects indicates that while immediate safety failures are being rectified, the underlying aging components and structural degradation are not being fundamentally addressed. With a recorded mileage of 250,137 miles over approximately 27 years, the vehicle has averaged roughly 9,264 miles per year. This is considered typical usage for a vehicle of this age and suggests a consistent history of regular road use rather than long periods of neglect or excessive high-speed motorway transit. From a mechanical standpoint, this level of mileage means that while the engine may have been well-maintained, the vehicle is deep into its lifecycle regarding high-wear components. You should expect significant cumulative wear on the suspension system, drivetrain mounts, and various rubber seals and bushings, which are prone to hardening and failure at these intervals. The most critical area for a prospective buyer to investigate is the ongoing corrosion noted on the front integral body structure cross member and the boot floor. Although the tester has noted that structural rigidity is not significantly reduced, corrosion is a progressive condition. During a test drive, pay close attention to any unusual rattles or creaks from the rear of the car, which could indicate the boot floor's integrity is weakening. Furthermore, the history of suspension ball joint play and steering rack gaiter issues suggests that the chassis and steering components are nearing the end of their service life. You should listen for any clunking or knocking sounds when navigating uneven surfaces or turning the steering wheel, as these are classic symptoms of worn suspension bushes or failing ball joints. Given the age and mileage, you must also conduct a thorough physical inspection of the vehicle's consumables. Check the condition of all tyre sidewalls for perishing or cracking, as age-related rubber degradation can occur even if tread depth remains legal. Inspect the brake discs for heavy pitting or uneven wear, and test the brake pedal feel to ensure there is no sponginess, which could indicate aged brake fluid or internal seal degradation. Additionally, verify the service history for evidence of regular fluid changes, specifically the transmission fluid and coolant, as these are vital for the longevity of a high-mileage luxury saloon. Finally, check the underside for any signs of fresh fluid leaks from the engine or gearbox, which often become more prevalent as gaskets and seals age.
