Yes, some small factories don't have a contract when they receive the deposit. They only have a receipt, no delivery date and no after-sales guarantee. Once the deposit is paid, if you don't mention the car under special circumstances, the deposit won't be refunded at all. Therefore, if you want to buy a car, you should go to a qualified and powerful regular manufacturer. You must sign the contract before paying the deposit, and then sign it after reading the terms carefully.
