The numbers

What this means if you are buying one

A 89.4% first-time pass rate means roughly 11 in every 100 Ford Fiesta St Performance Ed Turbos 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 Ford Fiesta St Performance Ed Turbo tested had covered 26,893 miles and was built around 2020.

What this means at salvage auction

Pass rate is a proxy for what a car costs to keep on the road. The Ford Fiesta St Performance Ed Turbo sits 12.7 points above the national average, ranked 805 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.
