If you own or are considering buying a 1983 Mercedes 240, budget for potential repairs before each MOT. 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 an average mileage of 185,675 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.
Seat Belts and Supplementary Restraint Systems — 1.7% of failures
Seat Belts and Supplementary Restraint Systems issues account for 1.7% of MOT failures on 1983 Mercedes 240 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.
Suspension — 1.4% of failures
Suspension issues account for 1.4% of MOT failures on 1983 Mercedes 240 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.
Lamps, Reflectors and Electrical Equipment — 1.0% of failures
Lamps, Reflectors and Electrical Equipment issues account for 1.0% of MOT failures on 1983 Mercedes 240 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.
