What this means if you are buying one

A 90.2% first-time pass rate means roughly 10 in every 100 BMW 320i M Sport Autos 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 BMW 320i M Sport Auto tested had covered 27,818 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 BMW 320i M Sport Auto 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 BMW 320i M Sport Auto 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 BMW 320i M Sport Autos actually sold for at UK salvage auction.
