About This Data
The 1974 Reliant Unclassified has an MOT pass rate of 75.0% based on 36 tests — above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 20,525 miles on the odometer. With a 25.0% failure rate, the 1974 Unclassified is rated as "Very Good" for MOT reliability.
If you own or are considering buying a 1974 Reliant Unclassified, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to suspension: 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. With relatively low average mileage of 20,525 miles, many of these vehicles are still in good mechanical condition.
Suspension — 11.1% of failures
Suspension issues account for 11.1% of MOT failures on 1974 Reliant 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.
Brakes — 11.1% of failures
Brakes issues account for 11.1% of MOT failures on 1974 Reliant Unclassified 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).
Body, chassis, structure — 2.8% of failures
Body, chassis, structure issues account for 2.8% of MOT failures on 1974 Reliant Unclassified models. Body and structure failures include excessive corrosion, sharp edges, loose panels, and damage to the vehicle frame. Rust is the primary concern, especially on older vehicles or those exposed to road salt. Typical repair costs: £100–500+. Pre-MOT check: Inspect sills, wheel arches, door bottoms, and the chassis for rust. Surface rust is acceptable but structural corrosion or holes will fail. Check that all doors, bonnet, and boot close securely.
