What does it mean to buy a car by rent?

It is a commercial form of leasing instead of buying.

In the field of real estate, developers lease commercial houses that are idle for sale to tenants and sign sales lease contracts. Tenants can buy houses within a certain period of time and use the rent to offset part of the house price. This method is suitable for families with insufficient funds at first and the ability to buy after their income increases.

In the field of automobile industry, some enterprises have also launched a new business model of "purchasing by rent". Car rental includes direct car rental business, car rental+buying and selling, car rental and purchasing integration, car booking service and other business forms.
