how do car traders make profit?

Answer 1

Traders or sellers????

Like used car dealers, what they do is commonly referred to as merchanting. They'll buy cars for cheap from a "supplier" and sell to people for a profit, about 2-3 sells in a month and you break even.

If you ever watch the move, Flywheel, you might get a better understanding as to how its done.

Car trading is a little more complex, but its the same idea.

Answer 2

Do you mean car dealers? If you do, they first get a discount from the manufacturer, then increase the price high enough to 'deal' with for another profit, then add preparation charges, and finally try to get the buyer to add options to the car. If that wasn't enough, they make certain that the customer have to use their service facility to fix any problems.

Answer 3

Buy at wholesale prices and sell at retail prices. Wholesale is 50 to 80 percent less than the cost of retail. They make the profit on the difference.
