The 1985 Rolls-Royce Corniche has an MOT pass rate of 87.4% based on 191 tests — well above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 67,422 miles on the odometer. With a 12.6% failure rate, the 1985 Corniche is rated as "Excellent" for MOT reliability.
The leading cause of MOT failure for the 1985 Rolls-Royce Corniche is Brakes, responsible for 2.1% of failures. 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 range from £150–400. Lamps, reflectors and electrical equipment is the second most common issue at 1.0%. Noise, emissions and leaks follows at 1.0%.

About This Data
The 1985 Rolls-Royce Corniche has an MOT pass rate of 87.4% based on 191 tests — well above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 67,422 miles on the odometer. With a 12.6% failure rate, the 1985 Corniche is rated as "Excellent" for MOT reliability.
If you own or are considering buying a 1985 Rolls-Royce Corniche, 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). At 67,422 average miles, these vehicles are in the mid-range where component wear starts to become a factor.
Brakes — 2.1% of failures
Brakes issues account for 2.1% of MOT failures on 1985 Rolls-Royce Corniche 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).
Lamps, reflectors and electrical equipment — 1.0% of failures
Lamps, reflectors and electrical equipment issues account for 1.0% of MOT failures on 1985 Rolls-Royce Corniche 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.
Noise, emissions and leaks — 1.0% of failures
Noise, emissions and leaks issues account for 1.0% of MOT failures on 1985 Rolls-Royce Corniche 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.
