About This Data
The 1983 Reliant Unclassified has an MOT pass rate of 53.1% based on 32 tests — below the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 23,778 miles on the odometer. With a 46.9% failure rate, the 1983 Unclassified is rated as "Poor" for MOT reliability.
If you own or are considering buying a 1983 Reliant Unclassified, be prepared for above-average maintenance costs. Before your MOT, pay particular attention to seat belts and supplementary restraint systems: Pull each seat belt fully out and check for fraying, cuts, or fading. Ensure each belt retracts smoothly and the buckle clicks securely. Check the pre-tensioner warning light on the dashboard. With relatively low average mileage of 23,778 miles, many of these vehicles are still in good mechanical condition.
Seat belts and supplementary restraint systems — 6.3% of failures
Seat belts and supplementary restraint systems issues account for 6.3% of MOT failures on 1983 Reliant Unclassified models. Seat belt failures include frayed or cut webbing, faulty retractors, buckles that don't latch properly, and missing or damaged anchorages. All fitted seat belts must be functional. Typical repair costs: £50–200 per belt. Pre-MOT check: Pull each seat belt fully out and check for fraying, cuts, or fading. Ensure each belt retracts smoothly and the buckle clicks securely. Check the pre-tensioner warning light on the dashboard.
Tyres — 3.1% of failures
Tyres issues account for 3.1% of MOT failures on 1983 Reliant Unclassified models. Tyre failures include tread depth below the legal minimum of 1.6mm, cuts, bulges, exposed cords, and incorrect tyre pressure. Tyres are one of the most common and easiest-to-prevent MOT failures. Typical repair costs: £50–200 per tyre. Pre-MOT check: Check tread depth with a 20p coin — if the outer band is visible, the tyre is too worn. Look for bulges, cuts, or embedded objects. Ensure all tyres match the recommended size and load rating.
Body, chassis, structure — 3.1% of failures
Body, chassis, structure issues account for 3.1% of MOT failures on 1983 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.
