Pass rate for Unclassified models manufactured in 1973, based on 197 real MOT test results.
Data from official DVSA MOT testing records
1973 Jaguar Unclassified MOT Analysis
The 1973 Jaguar Unclassified has an MOT pass rate of 77.2% based on 197 tests — well above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 50,459 miles on the odometer. With a 22.8% failure rate, the 1973 Unclassified is rated as "Excellent" for MOT reliability.
The leading cause of MOT failure for the 1973 Jaguar Unclassified is Noise, emissions and leaks, responsible for 1.0% 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 0.5%. Suspension follows at 0.5%.

About This Data
The 1973 Jaguar Unclassified has an MOT pass rate of 77.2% based on 197 tests — well above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 50,459 miles on the odometer. With a 22.8% failure rate, the 1973 Unclassified is rated as "Excellent" for MOT reliability.
If you own or are considering buying a 1973 Jaguar Unclassified, 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. At 50,459 average miles, these vehicles are in the mid-range where component wear starts to become a factor.
Noise, emissions and leaks — 1.0% of failures
Noise, emissions and leaks issues account for 1.0% of MOT failures on 1973 Jaguar Unclassified 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 — 0.5% of failures
Lamps, reflectors and electrical equipment issues account for 0.5% of MOT failures on 1973 Jaguar Unclassified 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.
Suspension — 0.5% of failures
Suspension issues account for 0.5% of MOT failures on 1973 Jaguar Unclassified models. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. Typical repair costs: £200–500. Pre-MOT check: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks.
