That's about it. Please consider it.

*Payment will be the winning bid price plus, unfortunately, the vehicle inspection fee of ¥45,000 and the recycling deposit of ¥7,790.

★A considerable amount of money has been spent on this, so the listing price reflects that. Thank you for your understanding.

*Notes

①While vehicle inspection is welcome, please do not include your email address in the question section! Yahoo will delete it.

My email address is listed in my profile, so please email me directly there! I will not accept any other requests for vehicle inspection!

②Price negotiation is not possible! I will ignore such questions, so thank you for your understanding.

The following individuals will be refused bids!

1: Those with a rating of 30 or less and any negative feedback. However, if you wish to bid, please indicate your intention to bid in the question section! Otherwise, your bid will be deleted!

2: New users (including those with a rating of 30 or less). However, if you wish to bid, please indicate your intention to bid in the question section!

3: Those with a history of disputes in the feedback system.

4: Foreign nationals. (If it is discovered after the auction that the bidder is a foreigner, the bid will be canceled due to the bidder's fault. Please understand, as we have had significant problems in the past.)

5: Those with a history of frequent cancellations.

6: Those who cannot strictly adhere to the no-returns/no-refunds policy in private sales.

Please note that bids from the above individuals will be rejected and canceled!

★★Most Important: If you have few ratings and wish to bid, please be sure to communicate your intention to bid in the question section! Otherwise, your bid will be canceled.

★Things to be strictly observed!

★Please note that if there is no contact within 12 hours of the auction ending, the bid will be canceled due to the bidder's fault.

★We will arrange land transport, but in principle, the winning bidder is responsible for this.

The car has a low ride height, so we recommend raising it with adjustable suspension before land transport. (Currently, it is stock.)

Ideally, we would like you to drive it home.

For nearby locations, we can transport it by car carrier at cost.

★Direct pickup is welcome.

★We will also refuse bids from those who cannot complete payment within 3 days of winning the auction! (I'm open to discussion.)

★This is a private sale, so I cannot offer loans! I can assist with obtaining quotes for bank loans.

★I will decline bids from overly sensitive individuals. A cancellation fee of 10,000 yen will be charged regardless of the reason.

★As this is a private sale, please adhere strictly to the no-returns, no-refunds policy.

★I will not answer any questions regarding immediate purchase.

★If you wish to inspect the vehicle in person, please contact me directly using the email address listed in my profile. To avoid problems, I will decline vehicle inspections for those who cannot contact me directly via email.

I will answer any questions to the best of my ability.
