What on earth do you mean. Have you ever bought a car?

You negotiate the price you are willing to pay. The dealer has no idea if you are leasing, paying cash, or financing. The all-in price is either financed or leased at a specified interest rate. They do not "add in" an up front payment. That doesn't even make sense, and would be incredibly misleading.

If we negotiate $25,000 for the car,and I finance at 0%, you are saying they up the price to $27,500 to "build in a profit"? Nonsense. The numbers are in front of you and you can do the calculations yourself with high school math. 0% is 0%.

You are totally out of your element and shouldnt be providing financial advice. Maybe that's why the dealer rips you off.

You're wrong. Cash back rebate offers usually don't apply to the 0% apr deal, so the amount financed will be higher. Which option is better depends on the size of the rebate, what interest rate you can get outside the low apr deal, and the amount financed.

Edmunds has a calculator if you need help with the high school math: https://www.edmunds.com/calculators/incentives-rebates.html

If the choice is between you getting a "sweet deal" or the dealer making a profit, you will lose every time. Rebates and magic 0% interest are designed to get you to sign on the dotted line without reading the fine print.
