Due to the different use and technical maintenance of the same model, the color is different and the price is different. Because there is no uniform standard for the evaluation of used cars at present, how to correctly evaluate used cars has become a topic of great concern to consumers. Mastering some basic valuation methods of used cars will help to estimate the value of used cars more accurately and make the transaction price more reasonable. How to correctly evaluate used cars? Method 1: Mathematical calculation formula The most common evaluation formula is: the current price of the used car being evaluated = replacement price *( 1- service life/specified life) * 100%* adjustment coefficient. In this formula, the part of (1- service life/specified life) * 100% is called "innovation rate"; "Replacement price" refers to the lowest cost paid for buying a new car that is the same as the evaluated vehicle. This method is suitable for vehicles that are still on sale, and its adjustment coefficient is obtained by weighting each item of the vehicle. The more and more detailed the scoring items are, the closer the data is to the residual value of used cars, and the more accurate the evaluation is. In addition, there are "5432 1" method or "432 1" method. These methods are simple to operate, and the basic value of used cars can be obtained by simple calculation. Valuation Method 2: Online Valuation Method With the development of the Internet, people can also rely on online software to evaluate used cars. After all, car valuation is a systematic and professional job, which is difficult for inexperienced people to master under normal circumstances. If online valuation is carried out through network software, it will be easier. This kind of software is developed by designers with experience in valuation. Owners or buyers of used cars only need to input relevant data into these softwares, specify options according to the car condition, and then the software automatically generates the reference price range. As long as the data provided are reliable and accurate, the estimated price is still of reference significance. The disadvantage of this valuation method is that it cannot consider some special circumstances and can only make a fixed valuation according to software options. Appraisal Method 3: Appraisal Method of Professional Appraiser It is not easy for buyers or sellers to evaluate used cars, because they can't make a professional appraisal of their condition at all. But professionals who specialize in car valuation are different. They not only have the knowledge of automobile transaction price, but also have the knowledge of automobile quality inspection. They can make a more professional evaluation of the value of used cars according to the market price and the current car condition. If you can't negotiate the price and are afraid of being cheated, it is the best choice to find a professional appraiser. They will give you a reasonable appraisal report. Although it will cost a little money, you can buy a reasonable price suggestion. No matter which method is used to evaluate the reasonable value of the used car to be traded, it is to set a suitable price for the used car, so that not only the buyer can rest assured, but also the seller can get the corresponding benefit protection. How to correctly value used cars? Only used cars that have passed the valuation can buyers and sellers trade with confidence without fear of being cheated.
