Why does a car worth 120,000 only have an invoice of 90,000?

This practice is called under-invoicing, which is illegal. Merchants do this to evade taxes. To protect your rights, you can request a reissued invoice. When you notice a discrepancy between the car purchase price and the invoice price, keep all evidence and raise the issue with the 4S store. If they cannot provide a reasonable explanation, you can report it to the tax authorities or file a complaint with the consumer association. The dangers of under-invoicing include: 1. Car insurance: Mainly for comprehensive and theft insurance, where claims are only compensated based on the invoice amount. When selling the car as a used vehicle, depreciation is calculated from the invoice price, leading to undervaluation. 2. Claims: When making a claim, compensation is only based on the actual invoice price.
