That is better than average, so a well-kept example is a reasonably safe used buy. The average MG Zs Exclusive Vti-Tech tested had covered 24,231 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 MG Zs Exclusive Vti-Tech sits 13.6 points above the national average, ranked 646 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.
