1977 Triumph Stag Auto 3.0L Petrol · RPE 633R

The 1977 Triumph Stag is currently not roadworthy, as evidenced by its most recent MOT failure on 2023-03-03. The maintenance trend shows a worsening condition, particularly concerning structural corrosion and brake performance. While the vehicle passed in 2022, the 2023 failure highlights a significant deterioration in the suspension mounting areas and brake system reliability, indicating that previous repairs or maintenance were insufficient to address underlying issues. The recurring brake faults and suspension component corrosion suggest ongoing neglect or inadequate attention to critical safety systems. The recorded mileage of 81,720 miles over 49 years equates to an average of approximately 1,668 miles per year, which is relatively low for a vehicle of this age. This suggests the car has likely been driven infrequently or stored for extended periods, which can lead to dry rot in rubber components, degraded fluids, and rust accumulation. The MOT history shows consistent entries from 2019 to 2023, with no significant gaps, indicating regular testing but no clear improvement in mechanical condition. The mileage remained nearly static between tests, reinforcing the impression of limited use rather than active driving. Buyers should conduct a thorough in-person inspection focusing on the suspension components, particularly the corroded mounting areas on the sills and wheel arches, which are critical for structural integrity. The persistent brake pipe corrosion and grease contamination point to poor maintenance and potential fluid contamination risks. The fluctuating and lagging rear brakes, along with the worn steering rack joints and wheel bearings, indicate that the braking and steering systems require immediate attention. Additionally, the integral body corrosion, especially in the sills and floors, may compromise safety in a collision and should be assessed by a qualified mechanic before purchase.
