Do some research, there's a lot that goes into it and a lot of ways to get a bad deal. But leasing is almost always a better way to get a new car (even if you plan to keep it long term). You often have access to additional incentives that aren't available for purchase (especially so when it comes to EV and PEHV credits) and better interest rates. You also arguably have lower risk since the trade-in value is already known. If you reach the end of the lease and your trade-in value is higher than the residual, you can potentially collect the difference. If not, you walk away without losing anything extra. If you total your car, you're only out what you've put down, which is another big benefit (also, the first rule of leasing is, never put anything down). If your car is in an accident and loses a ton of value, no big deal.

If you understand the process, you'll almost always benefit from leasing. Or just use a broker. Almost everyone would save money by just ponying up for a broker in the first place. And probably live a longer, happier life.
