About This Data

The 2003 Smart Roadster has an MOT pass rate of 56.7% based on 30 tests — slightly below the UK average for UK vehicles. Cars of this vintage present for MOT with an average of 39,151 miles on the odometer. With a 43.3% failure rate, the 2003 Roadster is rated as "Below Average" for MOT reliability.

If you own or are considering buying a 2003 Smart Roadster, budget for potential repairs before each MOT. Before your MOT, pay particular attention to lamps, reflectors and electrical equipment: 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. With relatively low average mileage of 39,151 miles, many of these vehicles are still in good mechanical condition.

Lamps, reflectors and electrical equipment — 10.0% of failures

Lamps, reflectors and electrical equipment issues account for 10.0% of MOT failures on 2003 Smart Roadster 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 — 6.7% of failures

Brakes issues account for 6.7% of MOT failures on 2003 Smart Roadster 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).

Visibility — 6.7% of failures

Visibility issues account for 6.7% of MOT failures on 2003 Smart Roadster models. Visibility failures relate to the windscreen, wipers, washers, mirrors, and view-obstructing damage. Cracks in the windscreen swept area, ineffective wipers, or empty washer bottles are common causes. Typical repair costs: £10–300. Pre-MOT check: Check the windscreen for chips and cracks — damage larger than 10mm in the driver's swept area or 40mm elsewhere will fail. Test washers and wipers. Ensure both door mirrors are intact and adjustable.
