1977 Triumph Stag Auto 3.0L Petrol · SNR 176R

The vehicle presents a remarkably stable roadworthiness profile, maintaining a clean MOT record over the last five years. The most recent test conducted on 22 May 2025 at 83,718 miles resulted in no defects or advisories. This streak of clean passes dating back to 2021 suggests a consistent standard of maintenance and that the mechanical and structural components are currently operating within acceptable parameters. The mileage pattern is exceptionally low for a vehicle of nearly 50 years, averaging approximately 1,700 miles per year. Between May 2021 and May 2025, the car covered only 6,278 miles, showing a steady annual increase of roughly 1,500 miles between test intervals. This low usage indicates the car is likely used for occasional leisure outings rather than daily commuting, though such low mileage on older classics often masks the degradation of rubber-based components and fluid-related issues that occur through time rather than distance. Despite the clean digital history, a physical inspection must focus on the structural integrity of the chassis and Triumph Stag. A buyer should specifically check for hidden corrosion in the sills, floor pans, and suspension mounting points, as these are common failure points on this model that may not always trigger failures until advanced. Given the low mileage, inspect for perished brake hoses, seized caliper pistons, and perished suspension bushes. Paying close attention to the cooling system and engine seals is also vital to ensure that long periods of standing have not led to internal engine damage or coolant leaks.
