Lease Takeover For Lease Takeovers Can I Just Assume The Lease And Give The Car Back When The Lease Is Up?

For lease takeovers can I just assume the lease and give the car back when the lease is up? - lease takeover

Since I am trying to understand why some people have only a few months or in their cars and offer a lot of money as an incentive to take on his contract. I want a car for a very short (about 5 months) the rent and have no interest in buying when the lease. Can I give it to the agency as a normal lease?
