2007 Lexus IS250 2.5L Petrol · GU57 KXK

The vehicle is currently roadworthy but the maintenance trend shows a concerning decline regarding exhaust and structural integrity. While it passed its latest test in July 2025 at 136,730 miles, this followed a failure just two days prior at 136,708 miles. That failure was due to a blowing exhaust and a high lambda sensor reading, indicating a significant emissions fault that was only recently rectified. The persistent mention of underside corrosion across multiple years suggests an ongoing process of rust that has not yet been structurally addressed. At 136,730 miles over 19 years, the vehicle averages approximately 7,200 miles per year, which is consistent with typical usage for an older saloon. The mileage data shows steady progression, with roughly 2,600 miles covered between the 2023 and 2024 tests and another 2,600 miles between May 2024 and July 2025. This regular use suggests the car has not sat stationary, but the high mileage means rubber and rubber components are subject to age-related degradation. A buyer must conduct a thorough physical inspection of the chassis to determine the extent of the corrosion flagged in the 2025 record. The tester should look for deep pitting on the mounting points and fuel lines, as the underside rust is a recurring advisory item. The exhaust system requires close scrutiny to ensure the recent repair for the 2025 failure was a permanent fix rather than a temporary patch. Additionally, the repeated advisories for uneven tyre wear in 2022 and 2023 indicate potential alignment issues or worn suspension bushes that warrant a professional check of the front control arms and struts.
