FAQs

What mileage is too high for a 2018 I800?

The median tested example shows 65,890 miles. Anything far beyond that isn't automatically bad — a motorway-mile car with consistent service records often beats a low-mileage school-run car — but price accordingly and scrutinise the mileage trail for gaps or drops.
