When it comes to the question of whether car dealers have an obligation to fill up your car with gas after delivery, the answer is no. There are no regulations that require them to do so. However, if they do offer this service, it is considered a sign of their good will towards their customers. If they do not provide this service, you will need to go to the nearest gas station to fill up your car yourself. Car dealers offer a range of services including sales, parts, and after-sales service. They also have a uniform image and management standards which can help to enhance the brand image and promote the models of the car. When you purchase a new car, the dealership will provide you with important documents such as the car's certification of compliance, user manual, invoice, and 保修卡. These documents are necessary for you to register your car and for future maintenance and repairs.

Why should you buy a car from a car dealership? The main reason is that car dealers offer a more comprehensive and systemized service. You can purchase a car, have it delivered, and then go back to the dealership for any repairs or maintenance that may be needed. This can save you a lot of time and hassle. In addition, car dealerships often have special offers and discounts that you can take advantage of. They also have a reputation for providing quality service, which can give you peace of mind. However, it is important to note that not all car dealers are the same. You should do your research and choose a reputable dealership that has a good track record of customer satisfaction.

In conclusion, while car dealers are not obliged to fill up your car with gas after delivery, they may choose to do so as a gesture of goodwill. If they do not offer this service, you will need to go to the nearest gas station to fill up your car yourself. When you purchase a car, make sure to get all the necessary documents, including the certification of compliance, user manual, and invoice. Remember to choose a reputable car dealership that provides good service and has a good reputation. This will ensure that you have a positive experience when purchasing and maintaining your car.
