What's the difference between buying a car abroad and buying a car at home?

In China, there are generally only two common payment methods for buying a car, full payment and loan. These two payment methods are easy to understand. Full payment means paying off the car in one lump sum when buying a car. A loan is to find a bank to pay in installments. The bank will give all the car money to the 4S shop, pay the down payment by itself, then take out the car first, and then slowly settle the car money every month. Unlike China, there is another way to buy a car in Canada-leasing, besides full payment and installment loan. This concept is not very easy to understand. Some people in China call it "long-term rent" or "car rental". This way is very different from the way of renting a car in our country. Leasing is actually a way of renting before buying.
