porsche with porsche financial on a lease

You would need to buy the car in order to sell it to another party - as technically, it's not yours to sell as the lessor. Which means, you'll likely need to pay sales tax on the residual value (assuming you're at lease end) depending on your state laws.

You first read the lease to find out how you can get out of it.

Check with your leasing dealership if you don't understand the fine print. They will put you in contact with the correct people.
