About This Data
The 1983 Mitsubishi L300 has an MOT pass rate of 56.9% based on 123 tests — slightly below the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 51,109 miles on the odometer. With a 43.1% failure rate, the 1983 L300 is rated as "Below Average" for MOT reliability.
If you own or are considering buying a 1983 Mitsubishi L300, budget for potential repairs before each MOT. 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 51,109 average miles, these vehicles are in the mid-range where component wear starts to become a factor.
Brakes — 3.3% of failures
Brakes issues account for 3.3% of MOT failures on 1983 Mitsubishi L300 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 — 1.6% of failures
Body, chassis, structure issues account for 1.6% of MOT failures on 1983 Mitsubishi L300 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.
Identification of the vehicle — 1.6% of failures
Identification of the vehicle issues account for 1.6% of MOT failures on 1983 Mitsubishi L300 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.
