About This Data
The 1983 Opel Monza has an MOT pass rate of 72.2% based on 205 tests — above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 41,421 miles on the odometer. With a 27.8% failure rate, the 1983 Monza is rated as "Very Good" for MOT reliability.
If you own or are considering buying a 1983 Opel Monza, 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 41,421 miles, many of these vehicles are still in good mechanical condition.
Suspension — 10.2% of failures
Suspension issues account for 10.2% of MOT failures on 1983 Opel Monza 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 — 4.9% of failures
Brakes issues account for 4.9% of MOT failures on 1983 Opel Monza 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 — 2.4% of failures
Body, chassis, structure issues account for 2.4% of MOT failures on 1983 Opel Monza 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.
