Which year to buy? →
The 2005 MX-5's first-time pass rate of 78.5% sits slightly below the UK average of 80%, which is fairly typical for a nearly 20-year-old sports car—not a major red flag, but a sign of accumulated wear. However, the bigger concern is that 39.4% of these vehicles have recorded a dangerous defect at some point, well above what you'd want to see, so any pre-purchase inspection should be thorough and professional.
At a median mileage of around 52,000 miles for a car this age, these MX-5s have been relatively well looked after on average. The average vehicle has racked up 4.29 failures and 24.2 advisories over its MOT history, suggesting routine maintenance issues rather than structural problems—before buying, get a full history check and ask the seller specifically about brake and suspension work, as these tend to be the cost drivers on aging sports cars.
The 2005 Mazda Mx 5 has a decent first-time pass rate (78.6%), but a higher-than-average share of vehicles have had serious defects recorded — the individual vehicle's history matters a lot here.
These stats describe 5,082 vehicles as a group. The specific vehicle you're looking at could be the one good example or the one outlier. Run its registration to find out.
