Signing a car purchase contract is an important part of the car buying process. The contract should specify the vehicle brand, model, frame number, engine number and other information to ensure that the vehicle information is accurate. Price terms should be clear, including the bare car price, purchase tax, insurance premiums, licensing fees and other cost details, to avoid price disputes later. Delivery time and place also need to be clearly agreed, to prevent business delays in the delivery of the car. Also pay attention to the liability for breach of contract, such as the business late delivery, the vehicle does not match the agreement and other cases of compensation, as well as consumer breach of contract. In addition, gifts should also be specified in the contract, including the brand, model, number of gifts, etc., to protect their rights and interests.
