What is a main disadvantage of leasing a vehicle compared to buying a vehicle?

There’s no cut off with a lease, so buying a vehicle has a set price that you pay until you reach, where as leasing a vehicle means you make the same set payment for the time that you have the vehicle. So, let’s say the price of a vehicle is $15,000 or you can lease the same vehicle for $200 a month. If you have the car for 10 years... (120 months)... you have payed $15000 for buying the car but if you lease the car you would have payed $24,000
