Cars of this vintage present for MOT with an average of 48,091 miles on the odometer. With a 13.3% failure rate, the 1971 Avenger 1250 Deluxe is rated as "Excellent" for MOT reliability.

If you own or are considering buying a 1971 Hillman Avenger 1250 Deluxe, 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). With relatively low average mileage of 48,091 miles, many of these vehicles are still in good mechanical condition.

Brakes — 8.9% of failures

Brakes issues account for 8.9% of MOT failures on 1971 Hillman Avenger 1250 Deluxe 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 — 4.4% of failures

Lamps, Reflectors and Electrical Equipment issues account for 4.4% of MOT failures on 1971 Hillman Avenger 1250 Deluxe 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.

Exhaust, Fuel and Emissions — 2.2% of failures

Exhaust, Fuel and Emissions issues account for 2.2% of MOT failures on 1971 Hillman Avenger 1250 Deluxe 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.
