Alfa Romeo Spider MOT Reliability Overview
The Alfa Romeo Spider is a moderately popular vehicle in the UK, with 70,855 MOT test results recorded in our database spanning 49 manufacture years. It has an overall MOT pass rate of 63.4% and a failure rate of 36.6%, which is around the UK average of approximately 37%.
Based on this data, the Alfa Romeo Spider earns a "Average" reliability rating. The average Alfa Romeo Spider presents for MOT with approximately 69,935 miles on the clock. Manufacture year matters: 2011 models achieve the highest pass rate at 86.7%, while 1996 models have the lowest at 52.0%. This 34.7 percentage point difference suggests notable variation in build quality or component durability across production years.
The most common MOT failure for the Alfa Romeo Spider is Brakes, affecting 39.1% of all tests. 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. The second most common issue is Suspension at 32.8%. Tyres rounds out the top three at 16.9%. Together, these top 3 failure categories account for a significant portion of all MOT failures for this model.

💡 What does the warranty cliff mean?
The Alfa Romeo Spider shows a moderate increase in MOT failures after warranty. The 31% increase is typical — plan for gradual maintenance cost increases. Peak failure occurs at age 12 (43.2% fail rate).
Note: pass rates may improve for very old vehicles due to survivorship bias — only well-maintained cars remain on the road.

About Alfa Romeo Spider MOT Data
The Alfa Romeo Spider is a moderately popular vehicle in the UK, with 70,855 MOT test results recorded in our database spanning 49 manufacture years. It has an overall MOT pass rate of 63.4% and a failure rate of 36.6%, which is around the UK average of approximately 37%.
For Alfa Romeo Spider owners, these results suggest average reliability — some preparation before MOT can improve pass chances. Focus your pre-MOT checks on brakes and suspension 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 Spider is likely to perform.
Brakes — 39.1% of failures
Brakes issues account for 39.1% of MOT failures on the Alfa Romeo Spider. 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).
Suspension — 32.8% of failures
Suspension issues account for 32.8% of MOT failures on the Alfa Romeo Spider. 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 — 16.9% of failures
Tyres issues account for 16.9% of MOT failures on the Alfa Romeo Spider. 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.
