You’re spot on with the interest. We just got a car a couple weeks ago, ballpark 3.5% for 72 months, $0 down. A decade ago, we never would have taken that loan because our family hates loans (hates interest).

Now? No down payment for interest for us. Put that money in some mutual funds or futures. Seriously, even a financially illiterate person could toss it in a Fidelity ETF and make hundreds of times more than their checking account... all while still driving that new car.

Compound interest builds up real fast.

Compound interest is the eighth wonder of the world. He who understands it, earns it ... he who doesn't ... pays it.
