What this means if you are buying one

A 92.4% first-time pass rate means roughly 8 in every 100 Vauxhall Astra Business Edition Nav Ts 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 Vauxhall Astra Business Edition Nav T tested had covered 28,973 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. On a Vauxhall Astra Business Edition Nav T 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 Vauxhall Astra Business Edition Nav T rather than the model in general?
