One way to get out of a lease is to sell the car to a dealership or another private party. In California, the huge advantage of leasing over buying new, if you aren't going to keep the car for a long time, is that you don't pay the full amount of sales tax up front, rather you pay over the course of the lease. (for a primer on leasing, see my Lease Primer) If you turn the car in at the end, you only have paid sales tax on the part of the lease you used. If you sell or trade in the car early, you can potentially save a bunch on sales tax... if only it were easy.
