About This Data

The 1973 Rolls-Royce Silver Shadow has an MOT pass rate of 74.3% based on 342 tests โ€” above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 49,110 miles on the odometer. With a 25.7% failure rate, the 1973 Silver Shadow is rated as "Very Good" for MOT reliability.

If you own or are considering buying a 1973 Rolls-Royce Silver Shadow, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to brakes: Listen for squealing or grinding noises. Check brake pedal feel โ€” if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm). With relatively low average mileage of 49,110 miles, many of these vehicles are still in good mechanical condition.

Brakes โ€” 3.5% of failures

Brakes issues account for 3.5% of MOT failures on 1973 Rolls-Royce Silver Shadow models. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components โ€” any brake deficiency will result in an MOT fail. Typical repair costs: ยฃ150โ€“400. Pre-MOT check: Listen for squealing or grinding noises. Check brake pedal feel โ€” if it feels spongy or goes to the floor, have the system inspected immediately. Look at brake pad thickness through the wheel spokes (minimum 3mm).

Noise, emissions and leaks โ€” 0.6% of failures

Noise, emissions and leaks issues account for 0.6% of MOT failures on 1973 Rolls-Royce Silver Shadow models. Emissions failures occur when exhaust gases exceed legal limits for carbon monoxide (CO), hydrocarbons (HC), or particulate matter (diesel). Common causes include faulty oxygen sensors, clogged catalytic converters, or DPF issues on diesel vehicles. Typical repair costs: ยฃ100โ€“1,000+. Pre-MOT check: If the engine management light is on, get it diagnosed before the MOT. For diesel cars, ensure the DPF has completed a regeneration cycle. Regular servicing and using premium fuel before the test can help.

Suspension โ€” 0.6% of failures

Suspension issues account for 0.6% of MOT failures on 1973 Rolls-Royce Silver Shadow models. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. Typical repair costs: ยฃ200โ€“500. Pre-MOT check: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks.
