I've looked into the leasetrader.com option. It looks interesting, but
I worry there might be some cost I don't realize. Is it as easy as (1)
pick up the car, (2) pay the monthly payments until the end of the
lease (only about 4-6 months for what I want), and (3) return the car
and forget about it?

Or is there more to it? Repair costs? Tires? What happens if it gets
a ding in it?

Thanks,

Rick
