What this means if you are buying one

A 90.4% first-time pass rate means roughly 10 in every 100 Fiat 500 Rockstar 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 Rockstar Mhev tested had covered 21,640 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. On a Fiat 500 Rockstar Mhev bought as a 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 Fiat 500 Rockstar Mhev 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 what damaged Fiat 500 Rockstar Mhevs actually sold for at UK salvage auction.
