Although the old-school thought states that you should always pay cash for a car if you can afford it, times and opinions have changed.
For example, let’s say you find a deal to finance $40,000 to buy a car at 1.99% interest, although you also have the cash to buy it. But instead of paying cash for it, you can invest that same $40,000 in a mutual fund to make a 5% return. In this case, you’re making a net return of 3.01% on that $40,000, which not only negates the interest charges but also makes financing the more financially intelligent move.
So if you have the cash to buy the car outright, always compare the interest rates to determine what the better option might be.
