The 1991 Mazda MX-5 passes its first MOT 10.5 percentage points below the UK average at 69.5%, which is a meaningful gap that reflects the age and condition challenges of a 30+ year old sports car. More concerningly, nearly one in three of these vehicles (30.3%) has recorded a dangerous defect at some point, making this a real buyer consideration for anyone looking at the model.

These cars are running at around 125,000 miles on average, which is reasonable for their age, but they're clocking up an average of 4.15 failures per test and 17.3 advisories—well above what a healthy classic should show. Before purchasing, get a pre-buy inspection focused on the structural integrity and rust (a common MX-5 weakness), and factor in that routine maintenance costs will be steady.

The 1991 Mazda Mx 5 has a below-average first-time pass rate (69.5% vs ~80% UK average) — check the specific vehicle's full MOT history carefully before buying.

⚠️ Over 1 in 5 of these vehicles have had a dangerous MOT failure at some point — usually tyres or brakes, and often a one-off issue rather than a persistent problem. The group stats won't tell you which one you're looking at.

For context

⚠️ Below average. More vehicles in this cohort fail their first MOT than typical. Scrutinise this vehicle's history — look for recurring issues, not just the latest result.

🔧 Expect consumable spend. An average of 17.3 advisories per vehicle tells you wear items (tyres, brakes) get flagged regularly. Budget for them — they're not surprises.

🔍 The dangerous defect figure is real. Most are one-off tyre failures or brake issues — not structural problems. But it's exactly why checking the individual vehicle's history is essential, not optional.

These stats describe 6,863 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.
