About This Data
The 2003 Mercedes 320 Ce has an MOT pass rate of 60.0% based on 80 tests — slightly below the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 91,227 miles on the odometer. With a 40.0% failure rate, the 2003 320 Ce is rated as "Below Average" for MOT reliability.
If you own or are considering buying a 2003 Mercedes 320 Ce, budget for potential repairs before each MOT. 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 an average mileage of 91,227 miles, these vehicles are in the higher-mileage bracket where wear-related failures become more common.
Suspension — 10.0% of failures
Suspension issues account for 10.0% of MOT failures on 2003 Mercedes 320 Ce 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.
Tyres — 3.8% of failures
Tyres issues account for 3.8% of MOT failures on 2003 Mercedes 320 Ce 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.
Lamps, reflectors and electrical equipment — 3.8% of failures
Lamps, reflectors and electrical equipment issues account for 3.8% of MOT failures on 2003 Mercedes 320 Ce 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.
