Paying cash for cars always seemed stupid to me. You're gonna plop down $60,000 for a car and next month it'll be worth $50k, then in a year $40k. Seems like a shitty ass investment bros. Finance your cars at 0%, 1.9% and take your $60k and put it in an interest bearing account and draw 3-5% on it easy. Or if you're a risk taker put it in something that draws 8-10%. You'd be stupid not to use someone elses money for free or almost free to buy a depreciating asset.
With that said don't ever finance anything you can't afford to pay off the same day. Basically don't borrow money you don't have, but don't be retarded ... if someone is giving you $60k, interest free, take it.
