About This Data
The 1984 Mercedes 280 has an MOT pass rate of 66.8% based on 2,854 tests — slightly above the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 96,028 miles on the odometer. With a 33.2% failure rate, the 1984 280 is rated as "Good" for MOT reliability.
If you own or are considering buying a 1984 Mercedes 280, you can expect reliable MOT performance overall. Before your MOT, pay particular attention to body, chassis, structure: 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. With an average mileage of 96,028 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.
Body, chassis, structure — 0.6% of failures
Body, chassis, structure issues account for 0.6% of MOT failures on 1984 Mercedes 280 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.
Lamps, reflectors and electrical equipment — 0.6% of failures
Lamps, reflectors and electrical equipment issues account for 0.6% of MOT failures on 1984 Mercedes 280 models. Lighting failures cover all external lights: headlights, tail lights, brake lights, indicators, fog lights, and reflectors. A single blown bulb will cause an MOT fail. This is one of the most preventable failure categories. Typical repair costs: £5–50. Pre-MOT check: Walk around the car and check every light — headlights (dipped and main beam), side lights, tail lights, brake lights, indicators, hazard lights, reverse light, rear fog light, and number plate lights. Replace any blown bulbs before the test.
Brakes — 0.6% of failures
Brakes issues account for 0.6% of MOT failures on 1984 Mercedes 280 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).
