Home GlossaryAuction Grade

Importing

Auction Grade

A standardized condition rating (1-5, plus S for new) used at Japanese car auctions. Grade 4+ is excellent; 3.5 is average with minor issues; below 3 indicates significant wear or damage. The auction sheet also details specific defects with location codes. Never buy below grade 3 for import.

Related Terms

JDM (Japanese Domestic Market)

Vehicles manufactured for sale exclusively in Japan. JDM cars often have different specifications than export models — right-hand drive, Japan-only engines, unique trim levels, and stricter emissions equipment. The term is frequently misused to describe any Japanese-brand car.

Shaken (車検)

Japan's mandatory vehicle inspection required every 2 years (3 years for new cars). Covers safety, emissions, and roadworthiness. Shaken costs escalate as cars age, which is why many Japanese owners sell cars at 5-7 years — creating the supply of well-maintained used JDM cars for export.
