2005 Lexus IS250 2.5L Petrol · HG55 MUW

The vehicle currently holds a valid MOT following a pass on 8 May 2026 at 129,966 miles. The maintenance trend shows signs of recent improvement after a period of significant mechanical and structural decline. A failure on 1 April 2026 highlighted issues with exhaust emissions, a central front exhaust leak, and insufficient service brake efficiency. The successful retest just over a month later suggests these specific faults were addressed, moving the vehicle from a failing state to a compliant one. The recorded mileage of 129,966 over 21 years averages approximately 6,189 miles per year, which represents typical usage for a vehicle of this age. The data shows consistent movement, with 3,344 miles covered between the January 2025 test and the April 2026 failure. This steady accumulation suggests the car has been in regular use rather than sitting idle for long periods, which helps mitigate some risks associated with seized components or perished rubber seals. A buyer must scrutinise the vehicle's structural integrity and suspension components due to serious historical issues. The December 2023 failure recorded both offside and nearside rear Macpherson struts as corroded and seriously weakened. While the sub-frame corrosion noted in late 2023 was described as not seriously weakened, the severity of the strut failure indicates a history of significant rust. It is essential to inspect the rear suspension mounting points and the sub-frame for any signs of advancing oxidation or recent remedial welding. The exhaust system also requires close attention. The record shows a recurring pattern of leaks, with the offside front exhaust flagged in December 2023 and a central front leak appearing in April 2026. Given the recent failure regarding the Lambda reading and exhaust gases, the buyer should check for any remaining leaks or signs of makeshift repairs. Finally, the brake efficiency failure in April 2026 warrants a physical inspection of the discs, pads, and calipers to ensure the braking system is performing consistently and is not prone to binding or uneven wear.
