1992 MG Roadster MOT Analysis
The 1992 MG Roadster has an MOT pass rate of 65.9% based on 44 tests — slightly above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 53,413 miles on the odometer. With a 34.1% failure rate, the 1992 Roadster is rated as "Good" for MOT reliability.
The leading cause of MOT failure for the 1992 MG Roadster is Lamps, reflectors and electrical equipment, responsible for 9.1% of failures. 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 range from £5–50. Tyres is the second most common issue at 4.5%. Noise, emissions and leaks follows at 4.5%.

About This Data
The 1992 MG Roadster has an MOT pass rate of 65.9% based on 44 tests — slightly above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 53,413 miles on the odometer. With a 34.1% failure rate, the 1992 Roadster is rated as "Good" for MOT reliability.
If you own or are considering buying a 1992 MG Roadster, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to lamps, reflectors and electrical equipment: 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. At 53,413 average miles, these vehicles are in the mid-range where component wear starts to become a factor.
Lamps, reflectors and electrical equipment — 9.1% of failures
Lamps, reflectors and electrical equipment issues account for 9.1% of MOT failures on 1992 MG Roadster 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.
Tyres — 4.5% of failures
Tyres issues account for 4.5% of MOT failures on 1992 MG Roadster models. Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure. Tyres are one of the most common and easiest-to-prevent MOT failures. Typical repair costs: £50–200 per tyre. Pre-MOT check: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating.
Noise, emissions and leaks — 4.5% of failures
Noise, emissions and leaks issues account for 4.5% of MOT failures on 1992 MG Roadster 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.
