Experts recommend focusing on the actual needs of car deployment Various brands on the market will launch models with different configurations. How to choose the right vehicle configuration for a car purchase has also become a headache for many consumers. A recent survey shows that many consumers are currently experiencing over-allocation problems during car purchases. Experts suggest that when choosing a car, it is important to note that the higher the configuration, the better. Consumers should focus on their actual needs to buy a car that suits their needs.

Many consumers tend to think that the higher the configuration, the better. In fact, some configuration may be useful, but the frequency of use is very low, or the actual value is not so great, in the process it is over-configured Happening. The largest car website in China, Car House, recently conducted a special survey on the allocation and use of cars, screening out 18 representative over-provisions, and constructing an over-configured index through mathematical modeling to match the degree of excessive configuration. It then proposes guidance for consumers to choose vehicle configurations to avoid unnecessary waste of value. In the survey, questionnaire surveys were conducted. The total number of questionnaires issued was 8,402, with 8,204 valid samples, and the effective rate was 97.6%.

The Car House Research Center selected a representative 18 vehicle configuration with less than 30% ownership from hundreds of configurations, including zoned air-conditioning, keyless entry start-up systems, seat heating, driving mode selection, and remote control Start, panoramic sunroof, automatic parking system, car TV, etc. According to the questionnaire survey data, among them, 6 high-tech configurations have a low general ownership rate, and only the ownership of the driving mode selection system configuration exceeds 10% to reach 17%; in the configuration related to the seat configuration, 4 sit. Chair ownership of heating configuration was high, reaching 23.1%, followed by chair memory of 13.2%; in the 4 security/manipulation configurations, ownership of keyless entry/startup systems was higher, reaching 21.6%; and in 4 In other configurations, district air conditioners have a relatively high percentage of consumers' cars, reaching 29.5%, followed by panoramic sunroofs, and the ownership rate is 10.7%.

At the same time, according to the survey results, the use of these configurations is not very optimistic among the consumers who have the above-mentioned car configurations. According to the survey's unutilized rate (the proportion of consumers who have this configuration but rarely use it or not use it at all), the unused rate of the driving mode selection system configuration is as high as 70.6%, which means that every 100 people have 70 owners of this configuration rarely use this configuration or do not use it at all. In addition, the unused rate of the automatic parking system was 68.4%, the unused rate of chair heating was 63.7%, the non-use rate of the car TV was 54.9%, the unused rate of the automatic parking was 39.7%, and keyless entry/ The unused rate of the boot system was 3.9%. It can be seen from the above that except for the better use of the keyless entry/start system configuration, there are cases in which other configurations cannot be used. According to the analysis of data by Car House Research Center, driving mode selection, seat heating, automatic parking system, lane departure assist system, car TV, engine start-stop technology, night vision system, seat massage, district air-conditioning and Chair ventilation became the top 10 in the over-allocation list.

Car House Research Center, the relevant experts said that the results of this study show that the higher the car configuration, the more comprehensive it must be a better mistake, but also reflects the typical "face" psychology. It does not take into account whether these configurations are really useful for the consumer's own car life and whether the price/performance ratio is appropriate. Experts suggest that when choosing a vehicle, consumers should not be excessively pursuing expensive and complete configuration, but should choose their own configuration, because only a proper decorative configuration can achieve the effect of safety, comfort and convenience, while achieving economical optimize.
