1971 Sunbeam Alpine MOT Analysis
The 1971 Sunbeam Alpine has an MOT pass rate of 67.2% based on 67 tests — slightly above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 38,009 miles on the odometer. With a 32.8% failure rate, the 1971 Alpine is rated as "Good" for MOT reliability.
The leading cause of MOT failure for the 1971 Sunbeam Alpine is Noise, emissions and leaks, responsible for 3.0% of failures. 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 range from £100–1,000+. Lamps, reflectors and electrical equipment is the second most common issue at 3.0%.

About This Data
The 1971 Sunbeam Alpine has an MOT pass rate of 67.2% based on 67 tests — slightly above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 38,009 miles on the odometer. With a 32.8% failure rate, the 1971 Alpine is rated as "Good" for MOT reliability.
If you own or are considering buying a 1971 Sunbeam Alpine, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to noise, emissions and leaks: 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. With relatively low average mileage of 38,009 miles, many of these vehicles are still in good mechanical condition.
Noise, emissions and leaks — 3.0% of failures
Noise, emissions and leaks issues account for 3.0% of MOT failures on 1971 Sunbeam Alpine 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.
Lamps, reflectors and electrical equipment — 3.0% of failures
Lamps, reflectors and electrical equipment issues account for 3.0% of MOT failures on 1971 Sunbeam Alpine models. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail. This is one of the most preventable failure categories. Typical repair costs: £5–50. Pre-MOT check: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test.
