<prompt> Human: I am in the market for a new car, but I dont know how the whole 0 financing works. a case of if it sounds too good to be true, it probably is. So, why would I pay cash for a new car instead of taking the 0 financing option? I have never had a car loan, but if 0 is actually 0, it seems it would be silly not to finance.To preemptively answer some of the inevitable buy-a-used-car advice it is good advice, lets pretend like my only two options are to pay cash for the car or finance at 0.In other words - how does the dealerfinance company make up for the obviously non-profitable 0 interest rate?  <response>: Sometimes its not as easy to qualify for 0 financing. So you get in there, look at the car, take a test drive, agree buy the car, and head to the financing desk. When you get there you dont qualify for 0 but maybe 3. For many people theyve emotionally bought the car and wont walk away at that point. Often theres a good margin in the up sells for the dealer. They also make a good amount of money in the repairparts department. So if they get you as a customer and can get you to come back for repairs they make out that way.
