The 1971 Morris Minor has an MOT pass rate of 66.8% based on 1,770 tests — slightly above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 45,416 miles on the odometer. With a 33.2% failure rate, the 1971 Minor is rated as "Good" for MOT reliability.
The leading cause of MOT failure for the 1971 Morris Minor is Body, chassis, structure, responsible for 0.2% of failures. Body and structure failures include excessive corrosion, sharp edges, loose panels, and damage to the vehicle frame. Rust is the primary concern, especially on older vehicles or those exposed to road salt. Typical repair costs range from £100–500+. Noise, emissions and leaks is the second most common issue at 0.2%. Brakes follows at 0.1%.

About This Data
The 1971 Morris Minor has an MOT pass rate of 66.8% based on 1,770 tests — slightly above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 45,416 miles on the odometer. With a 33.2% failure rate, the 1971 Minor is rated as "Good" for MOT reliability.
If you own or are considering buying a 1971 Morris Minor, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to body, chassis, structure: Inspect sills, wheel arches, door bottoms, and the chassis for rust. Surface rust is acceptable but structural corrosion or holes will fail. Check that all doors, bonnet, and boot close securely. With relatively low average mileage of 45,416 miles, many of these vehicles are still in good mechanical condition.
Body, chassis, structure — 0.2% of failures
Body, chassis, structure issues account for 0.2% of MOT failures on 1971 Morris Minor models. Body and structure failures include excessive corrosion, sharp edges, loose panels, and damage to the vehicle frame. Rust is the primary concern, especially on older vehicles or those exposed to road salt. Typical repair costs: £100–500+. Pre-MOT check: Inspect sills, wheel arches, door bottoms, and the chassis for rust. Surface rust is acceptable but structural corrosion or holes will fail. Check that all doors, bonnet, and boot close securely.
Noise, emissions and leaks — 0.2% of failures
Noise, emissions and leaks issues account for 0.2% of MOT failures on 1971 Morris Minor 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.
Brakes — 0.1% of failures
Brakes issues account for 0.1% of MOT failures on 1971 Morris Minor 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).
