A few folks have said in this thread they can't find 2% interest. Let me help you, American Express Bank (the arm that basically funds the purchases people make on their CC's) offer 2% for a small initial deposit, not an intro rate, FDIC insured. So that's your opportunity cost (you can actually get a little higher than that today, maybe 2.5% max with 0 risk; IE, FDIC insured). You give up that 2% if you pay cash for anything. Can you finance for less than that? Depends on the company. But, if the cash discount is less than 2%, and/or the APR is under 2%, you should finance, 100% of the time, and keep the money in the bank/stock market/bonds/etc.
Whenever I buy something new, it's a simple calculation to figure out if I should finance it or not. A few years back, almost everything should be financed because interest rates were so low. I took out 84 month+ loans on things that are making me a lot of money today because the money I would have spent is still sitting in my bank account. If it's 0% and there's no cash discount, the only question that should come next is "how long can I finance it for at 0%". 3 years, 5 years? Shoot, give me a 100 year 0% loan and I'll buy a 100HP skid and a matching excavator today (are you listening Kubota? Please feel free to reach me by PM!!).
Listen, dealers and OEMs do stupid things sometimes. My F150 is leased because, at the time, Ford was offering an effective .5% (yes, you're reading that right) on leases but 1.9% on financing. Yeah, that's just stupid, a lease is financing something with a put option (a guaranteed right to return it at a predetermined price and time), it should ALWAYS cost more because it's a safer product for the consumer (pay cash, drive the truck off the lot and it's stolen, you're in a world of hurt.. If it's leased, all leases have gap protection, you might not even make your first payment, just go back and get another one). However, my wife's SUV was financed (.9%) because they offered no cash discount and lease rates were higher. And my tractor (Kioti NX6010) I paid cash for because their low interest financing would mean I had to pay for the loader (5K) and their normal interest financing was stupid high (5.9% at the time, IIRC). Leasing was not an option.
There's no "right answer". All these financial products have a place, and all of them can be great deals or horrible ones. 0% financing for 3 years on a 30K car where you paid 5K more than the guy paying cash? Terrible deal. Same financing where you got the cash price? Great deal. With car dealers, always, always start off with "I'm looking at paying cash, but, if you can offer me good financing, I'll consider it". Get the cash price, compare that to something like KBB or invoice to see where you are and then get the finance details (APR for buying, money factor and residual for leasing).
My truck was actually a really silly lease, 2 years, 24K miles. I fully intended to buy this truck when I walked into the dealership, but, hey, if you're willing to float me 65K for 2 years for basically nothing, plus take the risk of theft, totaling the truck, having major problems that lead me to want another vehicle?? Well, sure, I'm going to do that and you (Ford) are kind of stupid for making that deal but who am I to complain?
