The advantage of renting a car is 1, which is flexible. Rent the car when you need it and return it to the car rental company when you don't need it.
2, convenient, after all, the rented car is not your own, and car maintenance, annual inspection and other things do not need the participation of the renter.
3, do not occupy funds, if you buy a car, you need long-term capital flow, or invest a lot of money at one time. And these occupied funds are mostly costs.
4. Your car will age gradually. Just return it to the car rental company when it's used up. You can rent a new car every time.
