Car dealers selling sheep's head to sell dog meat in the used car market in a circle, just like in the vegetable market, only one word to describe their enthusiasm is "sticky." When reporters asked for the used car price as a car buyer, these people exceeded their enthusiasm. Almost every car seller said that they were their own car, but when you look at the vehicular traffic permit, you will find that most of the vehicles are driving. The owner of the certificate is not a car seller. Thus, the sellers of car sellers have also said that they are reselling friends or relatives. In fact, the people who really sell cars rarely go to the market to sell cars.
Similar in the informal second-hand car market, most of them use sheepskin to sell dog meat. Some bad car dealers either use low-grade models to convert to high-end configurations of the same models and sell them at high prices in the used-car market, or It is the re-listing and sale of vehicles after beauty.
Second-hand car conditioning, beauty is the unspoken rules of dealers to sell used cars Jiucheng received after processing and then changed hands to sell money, this may be higher profits. Mr. Li, who had just switched to the company, told reporters that beauty treatments such as watch adjustments, renovations, and renovations are unspoken rules in the used car industry. The most prominent is the adjustment of the odometer, which is already an open secret of used car trading. Mr. Li said that in some second-hand car dealers, 90 percent of the old car odometers have been tampered with, and adjustments have been made. It is not a difficult task for them. The adjustment of the odometer has a direct impact on the price of the vehicle, ranging from a few thousand to as many as tens of thousands. However, there are significant hidden dangers to the safety of consumers. For example, in the used car market, the odometers of such hot-selling models often encounter venomous hands.
Law enforcement officers of the Institute of Industry and Commerce, which used hard evidence to obtain evidence, told reporters that fraudulent use of second-hand cars can not be initiated. Vehicle failures are caused by many reasons. Apart from vehicle conditions, there are drivers’ driving techniques, and it is necessary to determine what causes vehicle breakdowns. It is very complicated to identify. Especially for used cars, due to the aging of components, it is more difficult to confirm the cause of the failure after a failure. Industrial and commercial personnel remind consumers to buy used cars in addition to normal outdoor use, but also signed a formal sales contract with used car dealers in case of disputes.
Analysis of the unspoken rules of the used car market
