How about Changan Auchan's new car insurance service? Has anyone bought it? Is it reliable?

The new car must be guaranteed first. Generally, the first insurance is free, so it is recommended to insure in advance, because there are many iron filings in the early stage of the new car, and if the maintenance is too late, it may increase wear and tear. Therefore, it is generally recommended that the new car travel about 3000 kilometers for maintenance and oil replacement. In the case of the second insurance, it is generally enough to drive about 5000 kilometers before the second insurance. However, it should be noted that the shelf life of engine oil is 6 months, so even if you don't drive 5000 kilometers, you should change the engine oil for more than 6 months. Isn't this car treasure only available in Changan Auchan's car? If your car also belongs to Chang 'an, you can wait for the specific feedback from the market.
