SEAT Arona: MOT pass rate and reliability data

The SEAT Arona passes its MOT first time more often than the average UK car, by 9.9 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 41,107 individual SEAT Arona tests. Nothing here is an estimate or a survey.

The numbers

First-time pass rate86.6%
UK national average76.7%
Difference+9.9 points
Tests analysed41,107
Average mileage at test33,960 miles
Average year of manufacture2019
Reliability rank1,126 of 2,005 models

What this means if you are buying one

A 86.6% first-time pass rate means roughly 13 in every 100 SEAT Aronas presented for MOT fail on the first attempt. That is better than average, so a well-kept example is a reasonably safe used buy. The average SEAT Arona tested had covered 33,960 miles and was built around 2019.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. The SEAT Arona sits 9.9 points above the national average, ranked 1,126 of 2,005 models. On one bought as repairable salvage, the mechanical side is less likely to spring surprises, so your repair estimate should hold up reasonably well.

Before you bid: run the lot through the analyzer, check the car's own record, check the mileage, decode the VIN, and if it carries a marker use the write-off value calculator. Or compare it against another model.

Looking at a specific SEAT Arona rather than the model in general? The free check covers its MOT and mileage history, and the full HPI report confirms the insurance write-off category, outstanding finance and whether it is recorded stolen, from licensed data for 5 credits. Already own one that has been damaged? Work out whether fixing it beats selling it with the repair or scrap calculator, and see recorded closing bids for damaged SEAT Aronas at UK salvage auction.
