I have an uncommon lease term of 36months at 15,000 miles per year. So my car has a low residual. Good if you want to but it at the end of the lease. I have a post in the For Sale section on this board too.

The other benefit to look for in Lease Assumption is if the current Lessee has the Safe Lease Insurance for Excess Wear. It is transferable for $25.
