2004 Ford Focus 1.6L Petrol · YY04 NVB

The vehicle is currently roadworthy but the maintenance history reveals a worsening trend regarding structural and mechanical degradation. While it passed the most recent test in November 2025 at 79,179 miles, the tester identified a new front oil leak and a severely deteriorated offside front outer drive shaft constant velocity boot. The persistent presence of corrosion across the sub-frame, suspension arms, and inner integral body structure indicates that the vehicle is suffering from advanced environmental oxidation that has not yet reached the point of failure. The mileage profile is exceptionally low for a 22-year-old vehicle, averaging approximately 3,600 miles per year. Between November 2022 at 63,704 miles and November 2025 at 79,179 miles, the car covered 15,475 miles. This low usage rate explains the observed condition of rubber components, such as the perishing nearside rear tyre noted in late 2024, which often occurs when a vehicle sits stationary for long periods rather than being subjected to regular road use. A buyer must prioritize a thorough inspection of the structural integrity, specifically the rear inner integral and sub-frame which have been flagged for corrosion for four consecutive years. Although the records state these are not yet seriously weakened, the recurring nature of these advisories suggests the metal is thinning. Mechanically, the front oil leak identified in the latest test requires immediate investigation to determine the source and prevent further damage, while the deteriorated CV boot must be replaced to avoid imminent drive joint failure.
