About Ferrari 400 MOT Data

The Ferrari 400 is a rare vehicle in the UK, with 523 MOT test results recorded in our database spanning 9 manufacture years. It has an overall MOT pass rate of 76.9% and a failure rate of 23.1%, which is well above the UK average of approximately 37%.

For Ferrari 400 owners, these results suggest a reliable vehicle that generally passes its MOT without major issues. Focus your pre-MOT checks on suspension and lamps, reflectors and electrical equipment for the best chance of a first-time pass. Use our detailed year-by-year breakdown and failure analysis below to understand how your specific 400 is likely to perform.

Suspension — 20.1% of failures

Suspension issues account for 20.1% of MOT failures on the Ferrari 400. 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 — 18.9% of failures

Lamps, Reflectors and Electrical Equipment issues account for 18.9% of MOT failures on the Ferrari 400. 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 — 17.4% of failures

Brakes issues account for 17.4% of MOT failures on the Ferrari 400. 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).
