About This Data
The 1974 MG Unclassified has an MOT pass rate of 66.3% based on 418 tests — slightly above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 50,107 miles on the odometer. With a 33.7% failure rate, the 1974 Unclassified is rated as "Good" for MOT reliability.
If you own or are considering buying a 1974 MG 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. At 50,107 average miles, these vehicles are in the mid-range where component wear starts to become a factor.
Suspension — 1.2% of failures
Suspension issues account for 1.2% of MOT failures on 1974 MG 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 — 1.0% of failures
Brakes issues account for 1.0% of MOT failures on 1974 MG 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).
Identification of the vehicle — 0.5% of failures
Identification of the vehicle issues account for 0.5% of MOT failures on 1974 MG Unclassified models. Identification failures relate to the Vehicle Identification Number (VIN) and registration plate. The VIN must be permanently displayed and legible, and the registration plate must meet British Standard formatting. Typical repair costs: £10–50. Pre-MOT check: Ensure the VIN plate is visible and legible (usually in the windscreen or under the bonnet). Check that number plates are clean, undamaged, and use the correct font and spacing.
