The engines stay in Japan. You look, you bid and you win, from your own phone. Payment and shipping go through your parent buyer. The record stays with the engine, so you can show it when you sell it on.
To register, open the invitation link your parent buyer sent you.

You can bid only up to your buying limit. The more you pay on time, the higher it goes.
| Rank | Engines at once (guide) | How to reach it |
|---|---|---|
| Bronze | 3 | Everyone starts here |
| Silver | 10 | 5 engines paid on time, none late |
| Gold | 20 | 15 engines paid on time, none late |
You place a deposit with your parent buyer, not on this site. Once your parent buyer confirms it, your limit appears on “My page”.
What you would pay for engines you have won but not paid for yet, plus for the lots where you are the top bidder now: the price plus fees, shipping and import tax.
“My page” always shows how much of your limit is left.
You pay after your engine is loaded, by the due date shown on “My page”. When your parent buyer marks the payment received, that amount is free again.
The amount is taken from your deposit, your bidding pauses, and your rank drops one step.
Every payment is kept in a record that cannot be rewritten (SHA-256). Paying on time is how you move up.
The number of engines is a guide. Your real limit also depends on your deposit and on your parent buyer. Check your rank and limit on “My page”.
This is an online auction of used engines that are kept in Japan.
You bid yourself, from your own phone, against other buyers.
You pay your parent buyer, and your parent buyer brings what you win to your port.
Some lots are auctioned while in transit: the yard loads them into a container first, and we auction them while the ship is on its way. They are delivered after the ship arrives, and we cannot promise an arrival date. These lots show "In transit", the container number and the shipping date (the loading date before the ship leaves).
Eight stages, in order, from the invitation to the day you sell the engine on. The coloured stages are the ones you do yourself.
A coloured stage is a stage where you act.
Every engine carries a QR tag. Behind it is the engine passport: the record made in Japan before the engine was taken out of the car. The start-up video, the stamp checked twice, the inspection, the grade, the damage map.

When you sell this engine on, in your own city or in another country, your buyer opens the same page and reads the same record.
The passport carries condition and history only. What you paid, and who you bought from, never appear on it.
As long as the QR tag is on the engine, any phone opens the page, in eight languages.
The video fingerprint (SHA-256) is recorded at upload, and any conversion of the video is logged as well. Your buyer can compare what they see with what was recorded.
You are not only buying an engine. You are buying a record you can hand to the next buyer.
A lot is one engine offered for sale. Every lot page shows the same seven things. Look at all of them before you bid.
Filmed in the car before the engine was taken out. Listen to it run.
The number on the engine is photographed twice: when it is registered and again when it reaches the yard. A tick means the two photos show the same number.
Mileage, starting, video, rust, sludge, crank. Read all six lines, not only the grade word.
A list of the parts still attached to the engine. Check that the part you need is one of them.
Every scratch and crack is marked on a drawing. Tap a mark to open its photo.
The passport is the public page that holds the whole record of this engine. Scan the QR to open it. It still opens after the engine reaches you.
Ask a question or ask for another photo from the lot page. Ask before the lot closes.

The page shows the lowest amount you can bid right now. Anything below it is refused.
Bids move in fixed steps. Use − and + to move one step at a time.
Every lot has a closing time. A bid placed in the last minutes pushes the closing time back, so the last bid can always be answered.
How much you may hold on live bids at one time is set by your parent buyer. Over that, your bid is refused and the screen tells you how much is left.
Once placed, a bid stands. If nobody outbids you, the lot is yours.
A statement is the list of what you owe. It is issued by your parent buyer, not by the auction.
Payment goes to your parent buyer, who writes the payment details on your page.
Your amounts can also be shown in your parent buyer’s currency as a guide. The rate used for that guide is set by your parent buyer.
What you win is loaded into your parent buyer’s container at the yard in Japan. A container is the steel box that goes on the ship.
The ship is booked by your parent buyer, who also handles the import at your end.
Any arrival time you are given is a guide, not a promise. Ports and weather move it.

Seven screens, in the order you meet them. Each one says where it opens and what to do on it.
Opens when you tap the invitation link.
You are never asked to choose a role. The invitation already places you under your parent buyer.
Opens by itself after you register, and each time you log in before you are approved.
If the status says suspended rather than waiting, ask your parent buyer.
The first screen after you log in.
Lots are listed with the one closing soonest at the top.
Opens when you tap a card. Read it from the top down, in this order.
Ask your questions well before the clock runs out. Once a lot has closed, ask your parent buyer instead.
Under “My page” in the menu.
Your buying limit and deposit are on this page too. You place the deposit with your parent buyer; it shows here once your parent buyer confirms it.
The statement button on your page.
The statement is issued in your parent buyer’s name. Where to pay is written on your page.
The container link on your page.
The container belongs to your parent buyer, so not everything inside it is yours.
Tell your parent buyer first, and they take it up for you.
Scan the QR on the engine, or open the passport page. It opens in your language.
Use the ask button on the lot page. Once a lot has closed, ask your parent buyer.

Yes. You place it with your parent buyer, not on this site. Your deposit decides how much you can have unpaid and in bidding at once. Pay on time and your limit grows.
No. You bid under the parent buyer who invited you.
New accounts are approved by your parent buyer. If it takes long, ask your parent buyer.
No. A bid cannot be taken back, so read the lot carefully first.
Nothing. You owe nothing, and you can bid again while the lot is open.
Yes. The QR on the engine opens the same page, in your language.
Always your parent buyer. The auction does not bill you.
This guide is in eight languages. Ask your parent buyer in your own language.
Yes. The page behind the QR is there for your buyer. Amounts and the seller are not on it.
