Troubles in which sellers hand over used cars but are never paid are spreading rapidly, and the abuse of bulk appraisal sites for car buybacks has emerged as a tactic common to unscrupulous dealers. A customer, identified as A, registered their beloved Land Cruiser on a bulk appraisal site and handed the car to a dealer that offered 10.3 million yen, only to have the dealer vanish without paying. In the case of Car Shop IKKI, which has drawn the most reports of damage, a customer identified as B registered an Audi A3 for sale through Car Sensor's bulk appraisal service, signed a contract in July with the shop after it offered 2 million yen against another company's top estimate of 1.9 million yen, and handed over the car, but the payment date on the contract was left blank and the shop stopped answering phone calls from September onward. The number of victims of nonpayment by IKKI known to this writer alone reaches about 50, and the shop had also been certified as a proper sales outlet by an industry body. Recruit, which operates Car Sensor, said it was aware of the trouble and had completely removed all pages related to IKKI on September 10, while MOTA said it has tightened its membership screening and suspends distribution for any buyback shop where problems are confirmed.
