2004 Ford Focus 1.6L Petrol · WU04 UXG

The vehicle is currently technically roadworthy but the maintenance history reveals a worsening trend regarding structural integrity. While the car passed its most recent test in March 2026 at 155,323 miles, this followed a failure just one day prior for a major exhaust leak and failed emissions. The persistent presence of corrosion across the underbody, fuel tank straps, and suspension components indicates that while immediate faults are being addressed to pass inspections, the underlying structural condition of the chassis is reaching a state of critical decay. At 155,323 miles, this 22-year-old Focus has averaged approximately 7,000 miles per year, which is consistent with low-intensity usage for its age. However, the record shows 8,464 miles covered between March 2024 and March 2025, and another 11,419 miles in the following year. This increase in annual mileage suggests the vehicle is being used more frequently recently, which accelerates wear on the already aging mechanical and structural components noted in the advisories. A buyer must conduct a thorough physical inspection of the rear inner wheel arches and sills. The record from March 2025 flagged excessive corrosion that significantly reduced structural strength in these areas, which was later reportedly covered with underseal. This is a common method used to mask deep rust, and an inspector should check for bubbling paint or thin metal. Further verify the state of the fuel tank straps, which have been noted as corroded for at least two years. Mechanical attention is also required for the braking and suspension systems. The history shows recurring issues with corroded brake pipes, a lagging rear service brake, and weakened suspension arms. Given that the oil leak has appeared in every single test since 2024, the source should be identified to ensure it is not worsening. The recent failure of the lambda sensor reading in 2026 also suggests the exhaust system or engine management may be nearing end of practical life.
