Recently, the fuel-powered vehicle market has seen a surge in aggressive low-price promotions, such as “buy a Sylphy for RMB 50,000” or “get a Civic for RMB 90,000,” drawing significant consumer attention. These advertised prices typically combine multiple conditions—including trade-in subsidies, national and local government incentives, and financing discounts—and do not reflect the actual transaction prices readily achievable by average consumers through standard purchasing procedures. In reality, very few buyers can simultaneously meet all the prerequisites required to qualify for these bundled discounts, making it extremely rare for anyone to actually purchase a vehicle at the advertised low price. Such marketing tactics have long persisted in the fuel-car market, contributing to confusion and disorder in terminal pricing. Despite frequent promotional campaigns, overall industry price reductions remain within manufacturers’ controlled limits, with no signs yet of a full-scale price collapse or destructive competition. Consumers who mistakenly treat these promotional prices as actual transaction prices risk falling into purchasing traps if they make impulsive buying decisions.
