While the decision to buy or lease a car can be a tricky one, a quick evaluation of your financial situation can help you decide which option is best. People who lease a car typically do so because it allows them to drive a newer car for less money than it would cost to buy one. According to the car experts at Edmunds, young adults are far more likely to lease. In fact, more than one-third of millennials in 2016 were opting for auto leases.
