2004 SEAT Leon 1.9L Diesel · DG54 RGO

The vehicle is currently roadworthy but the maintenance history reveals a worsening trend regarding structural integrity and mechanical neglect. While it passed the most recent test on 21 May 2026 at 223,109 miles, the report identified significant corrosion across the vehicle structure and suspension mounting points. This follows a serious failure in January 2026 where the tester found a hole in the offside front seat belt anchorage and floor pan. The presence of underseal covering structural repairs and mounting points suggests previous attempts to mask advanced rust issues rather than resolve the underlying degradation of the chassis. At 223,109 miles over 22 years, the car averages approximately 10,141 miles per year, which is consistent with typical usage for a vehicle of this age. The data shows consistent annual use, with roughly 4,600 miles covered between January 2026 and May 2026. However, the high mileage combined with the age of the vehicle has clearly accelerated the wear of components, evidenced by the repeated failures of coil springs, drive shaft boots, and steering gaiters within short two-year intervals. A buyer must conduct a thorough physical inspection of the sills, floor pans, and suspension mounting points to determine the extent of the rust hidden beneath underseal. The tester specifically flagged corroded lower suspension arms and corroded underbody components, which indicates the metal is thinning significantly. Attention is also required for the front brake discs, which were noted as pitted and scored in early 2026. Given the recurring history of fractured springs and split CV boots, the risk of further expensive mechanical suspension and drivetrain failures remains high.
