When you are buying a vehicle from Japan—whether through a local importer or directly via a portal like Beforward or SBT—you are essentially buying a piece of paper first. The auction sheet is the only impartial record of the car’s condition before it enters the hands of middlemen, clearing agents, and dealers who may have a vested interest in hiding its flaws.

1. The Hierarchy of Overall Grades

The "Overall Grade" is the large number (or letter) usually found in the top corner. It represents the inspector's holistic assessment of mileage, structural integrity, and cosmetic condition.

2. The "Grade R" Controversy

A Grade R car has had a structural part repaired or replaced. This could range from a simple fender replacement (minor) to a straightened chassis rail (major). A "clean" Grade R can be 20% cheaper than a Grade 4 while driving perfectly, but you must read the Inspector's Notes to ensure the chassis is straight.

3. Decoding the "Map" (The Diagram)

The car diagram is covered in codes. Here is the forensic translation:

4. The Inspector's Notes (The Trap)

This is the Japanese text section most foreign buyers ignore. This is where the skeletons are hidden. Inspectors write mechanical issues here that don't have codes.

Common critical notes to look for (translate these!):

• "Engine noise / Knocking sound"
• "Transmission slippage"
• "AC not cooling"
• "Rust hole in floorpan"
