2006 Lexus IS250 2.5L Petrol · NL06 PHX

The vehicle passed its most recent MOT test on 27 March 2023 with no defects or advisories recorded, which is a positive immediate indicator for a prospective buyer. However, evaluating the broader trend reveals a pattern that warrants careful attention. The 2023 pass followed a failure just three days earlier involving a damaged registration plate, an inoperative nearside front position lamp, and a seriously weakened nearside rear coil spring mounting at the base of the shock absorber. The 2022 test produced advisories for corroded brake pipes and rear subframe corrosion, while the 2021 test repeated these brake pipe and subframe advisories alongside a tyre nail and a battery insecurity issue. The 2020 cycle was particularly concerning, with a failure for insecure battery, ineffective wiper, and incorrectly aimed headlamps, followed by a pass that still noted wearing front brake pads, edge-worn rear tyres, corroded coil springs on all four corners, and further brake pipe corrosion. Overall, the maintenance trend is not stable; it shows a recurring theme of corrosion-related defects on suspension, braking, and structural components, which is characteristic of a twenty-year-old vehicle and should be expected to continue progressing. With 132,317 miles recorded over approximately twenty years, the annual usage of around 6,616 miles is broadly typical for the vehicle's age, though it sits toward the lower end of average. There are no obvious extended gaps in the MOT record that would suggest long periods of standing, and the mileage has accumulated fairly consistently given the regularity of annual tests. This level of use means the engine, transmission, and drivetrain have likely been worked sufficiently to remain in reasonable internal condition, and the vehicle is unlikely to have suffered the severe flat-spotted tyres, seized calipers, or degraded fluids associated with prolonged storage. That said, the moderate annual mileage combined with the vehicle's age still subjects it to substantial calendar-based degradation, particularly of rubber, coolant, and corrosion-prone steel components, irrespective of how far it has actually been driven. Given the recurring brake pipe and subframe corrosion advisories from 2020 through 2022, a prospective buyer should thoroughly inspect the underbody for any progression of rust. Pay particular attention to the brake lines running front to rear, looking for surface rust, pitting, or any signs of previous repair with copper or brass fittings. The rear subframe mounting points should be examined for structural integrity, and the coil springs on all four corners should be checked for cracks or severe corrosion, especially at the lower seat on the nearside rear where a spring mounting was previously deemed seriously weakened. On a test drive, listen for any clonking or knocking noises from the suspension over uneven surfaces, which would suggest worn bushes or compromised springs, and feel for any pulling to one side under braking that could indicate a binding caliper or a brake pipe that has deteriorated further. Headlamp aim and wiper effectiveness should also be verified, as both were failure items in 2020. Beyond the documented history, several age-related checks are essential for a vehicle of this vintage. The tyres, despite not being flagged recently, should be examined for sidewall cracking and perishing, which occurs regardless of tread depth on older rubber compounds. The 12V battery is a known weak point on this model, having been flagged as insecure in 2020 and 2021, and its age and state of charge should be verified, ideally with a load test. Brake discs should be inspected for lipping and corrosion, particularly given the 2019 advisory for pitted and scored discs all round, as standing moisture can quickly worsen surface rust on exposed iron. All fluids, including engine oil, coolant, brake fluid, and automatic transmission fluid, should be checked for age and condition, as calendar-based degradation affects their performance even on a low-mileage vehicle. Finally, a compression test or at least a thorough inspection of the 2.5-litre V6 for oil leaks, particularly from the valve cover gaskets which are known to seep on higher-mileage examples, would be prudent before committing to purchase.
