Uhm, you don't understand the logic.
If you have $10,000 in an account making 10.5% and you take that money out to buy a car, you are now making 0% interest on that money.
If you take a $10,000 loan from the bank at 6% interest and use that to buy the car, you are still making 10.5% interest on the money in the account, but 6% of it is being "offset" by the interest on the car loan.
Similarly, if you have $10,000 cash making NO interest, and are buying a car for $10,000, it would be better to put the money into an investment making 10.5% and then borrow the money for the car at 6%. You're making 4.5% interest on that $10,000, even after factoring in the 6% APY the car is costing you. Thus, you are making $450 per year simply by borrowing money from the bank instead of using your own money to buy the car.
It's simple math, and I'm a college dropout.
