What common faults should I watch for on JDM auction sheets?

Key faults to watch: radiator replacement or repairs (common on high-mileage cars), oil leaks noted at engine seams, suspension component wear marks, floor panel repairs (flood damage flag), rear quarter panel replacements (accident indicator), odometer irregularities, and any reference to engine smoke or turbo noise. Multiple X or XX marks on a diagram indicate serious structural or mechanical issues. Always request a translation of the written notes section.
