Is the Japanese auction sheet enough?

The Japanese auction sheet is the best condition report in the used car business. It is written by an independent inspector rather than the seller, it is unusually honest, and nothing in an Irish or British classified advertisement comes close to it.

It is also not enough on its own, for three reasons that are rarely explained to buyers: it measures less than people assume, the same grade means different things at different auction houses, and it is produced in minutes rather than hours.

What the number actually measures

The headline grade — S, 6, 5, 4.5, 4, 3.5, 3 and downwards — is principally an assessment of exterior and cosmetic condition. It is not a mechanical report. It is not a service history. It is not a warranty. Alongside it sit an interior letter grade and a condition map marking where on the body each scratch, dent, wave and corrosion point sits.

Repair history is a separate field. This catches people out constantly. A car can carry a respectable number and still have structural repair behind it, recorded as an R or RA marking rather than in the grade itself. A lower-graded car can have no repair history at all and simply be scruffy. Reading the number without reading the repair field tells you how the car looks, not what has happened to it.

A grade 4 is not a grade 4

Every auction house in Japan publishes its own inspection rulebook. The symbols and the scale are broadly similar, but the thresholds are not uniform, and the strictness varies by house.

The practical consequence is that the same physical car, presented at two different venues, can come out half a grade point apart. Some houses are known for marking consistently hard; a high grade from one of those is generally accepted as equivalent to a higher grade elsewhere. Smaller operations tend to be more generous. The auction house's own legend is the controlling document for any given sheet, not any general explanation of the scale.

So comparing two cars on their headline numbers, without knowing which house issued each sheet, is comparing two different measurements and treating them as one. A buyer working from a spreadsheet of grades and prices, without that calibration, will systematically overpay for cars from lenient houses and pass over better cars from strict ones.

The sheet is written in minutes

Japanese auctions move at a pace that is difficult to picture from outside. Cars pass through the hall in a matter of seconds each, and the inspection behind the sheet is correspondingly quick — thorough for what it is, but a walk around and a look, not a session on a lift.

That is not a criticism of the system. It is a wholesale market designed for trade buyers who understand exactly what the document is. The problem arises when the sheet crosses an ocean and gets treated as a full inspection report by someone who has never seen the car.

What an inspection adds

We can have a car looked at before we bid, beyond what the sheet records. That is the step most of the price difference between buying well and buying badly actually sits in.

An inspection is looking for two different things. First, confirmation: does the car in front of the inspector match the car on the sheet? Second, the categories the sheet was never designed to cover — how the engine sounds and behaves from cold, what the underside looks like from below rather than from beside, whether a hybrid system is healthy, and whether there is anything the inspector would not want in their own driveway.

It costs a little money and some time. Compared with the cost of finding out the same information after the car has spent six weeks at sea, it is not a close call. It is also the reason that buying an already-inspected car from us is not the same transaction as bidding on the same lot yourself.

Why we bid on so few of the cars we look at in Japan

We filter hard, and it is worth explaining what that means in practice rather than as a slogan.

There is a grade floor, and it is calibrated to the auction house rather than applied as a flat number, for the reason set out above. The repair-history field is checked separately from the grade, every time. The condition map is read properly rather than glanced at, because a marking in one place on a body panel means something quite different from the same marking somewhere structural. The inspector's written notes get translated and read, since they frequently contain the most useful sentence on the whole page. And where a car matters enough or the sheet leaves a question open, it gets inspected before we bid.

Most cars fail one of those tests. That is the expected outcome, not a sign that something is wrong with the market. Walking away at that stage costs us nothing beyond the time already spent. Buying the wrong car costs the customer for as long as they own it, and costs us for as long as they tell people about it.

We have written separately about the cars we walk away from, which covers the same discipline from the other direction.

What this means if you are buying

None of this is an argument against Japanese auctions. They remain the most transparent source of used cars available to an Irish buyer, and the sheet is the reason it is defensible to buy a car you have not stood beside.

It is an argument against treating the sheet as the whole answer. Three questions are worth asking about any Japanese car being offered to you, whoever is selling it. Which auction house issued the sheet? What does the repair-history field say, separately from the grade? And has anyone actually looked at this car beyond the sheet?

If the person selling it to you cannot answer all three, they are passing the risk to you and charging you for the privilege.

What we do

We read the sheet properly, calibrated to the house that wrote it, and we inspect beyond it where it matters. Cars that have already been through that process are in current stock. If you want a specific car found, sourcing is the same filter applied to a brief rather than to a forecourt.

For the mechanics of the route itself, see importing a car from Japan, and for how it compares with buying here, Irish used car or Japanese import.

Common questions

What does a Japanese auction grade actually measure?

The headline number is principally an assessment of exterior and cosmetic condition, made by an inspector working quickly to that auction house's own rulebook. It is not a mechanical report and it is not a warranty. Repair history is recorded separately from the numeric grade, as an R or RA marking, which means a car can carry a respectable number and still have structural repair behind it, and a lower-graded car can have none at all. The two fields have to be read together.

Is a grade 4 at one Japanese auction house the same as a grade 4 at another?

No. Each auction house publishes its own inspection rules, and the thresholds are not uniform between them. The same physical car can come out half a grade point apart at different venues, and some houses are known for consistently stricter marking than others. Comparing two cars on their headline numbers alone, without knowing which house issued each sheet, is comparing two different measurements and calling them the same.

What does a Japanese auction sheet not tell you?

Mostly things that require time and tools rather than a walk around. Engine and gearbox condition beyond the obvious, the state of a hybrid battery, intermittent electrical faults, the depth of the service record, corrosion in places not visible from a standing position, and anything that only shows up on a drive. The sheet is an unusually good starting point by international standards, but it is a condition report written in minutes, not a full inspection.

Can you get a car inspected before bidding at a Japanese auction?

Yes, and it is the single most useful thing that can be done between reading a sheet and committing money. An inspection carried out on our behalf before we bid can look at the things the sheet is not designed to cover and confirm the things it claims. It costs time and a little money, and it is far cheaper than discovering the same information after a car has spent six weeks at sea.

Why do you bid on so few of the cars you look at in Japan?

Because most cars at auction are ordinary and we are not obliged to buy any of them. Between a grade floor calibrated to the individual auction house, the separate repair-history field, the inspector's written notes, the condition map and an inspection where one is warranted, the majority of lots fail one test or another. Walking away costs us nothing at that stage. Buying the wrong car costs the customer for years.
