Fiat 500 Lounge Mhev: MOT pass rate and reliability data

The Fiat 500 Lounge Mhev passes its MOT first time more often than the average UK car, by 14.2 percentage points. These figures come from the DVSA's full year of anonymised MOT results, covering 7,000 individual Fiat 500 Lounge Mhev tests. Nothing here is an estimate or a survey.

The numbers

What this means if you are buying one

A 90.9% first-time pass rate means roughly 9 in every 100 Fiat 500 Lounge Mhevs 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 Fiat 500 Lounge Mhev tested had covered 20,186 miles and was built around 2021.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. The Fiat 500 Lounge Mhev sits 14.2 points above the national average, ranked 551 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.
