About This Data

The 1963 Bentley S 3 has an MOT pass rate of 88.2% based on 51 tests — well above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 45,128 miles on the odometer. With a 11.8% failure rate, the 1963 S 3 is rated as "Excellent" for MOT reliability.

If you own or are considering buying a 1963 Bentley S 3, 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 — 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 45,128 miles, many of these vehicles are still in good mechanical condition.

Brakes — 13.7% of failures

Brakes issues account for 13.7% of MOT failures on 1963 Bentley S 3 models. Brake-related failures include worn brake pads, corroded brake discs, leaking brake lines, and faulty brake servos. These are safety-critical components — any brake deficiency will result in an MOT fail. Typical repair costs: £150–400. Pre-MOT check: Listen for squealing or grinding noises. Check brake pedal feel — 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).

Exhaust, Fuel and Emissions — 2.0% of failures

Exhaust, Fuel and Emissions issues account for 2.0% of MOT failures on 1963 Bentley S 3 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: £100–1,000+. 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.

Non-component advisories — 2.0% of failures

Non-component advisories issues account for 2.0% of MOT failures on 1963 Bentley S 3 models. Non-component advisories issues are a common cause of MOT failure. Regular inspection and maintenance of these components helps ensure your vehicle passes its MOT. Typical repair costs: £100–400. Pre-MOT check: Have this system checked during regular servicing. Look for warning signs like unusual noises, vibrations, or dashboard warning lights.
