<prompt> Human: So Mercedes is offering their Smart car for a 99 a month lease Ive normally shied away from leases and figured Id just save up and pay cash for a car, but this seems really cheap.If you amortize the down payment over the three years, its about 125 a month for car ownership for three years, plus insurance but with no maintenance worries.Other info- I live in SF so parking is tight :-  <response>: I say do the math and compare to buying a reliable japanese economy car used right after a 3-year lease. When doing the math take into consideration that you will end up owning the japanese economy car and can sell it down the line. I get 40 MPG highway in my hondacompare the costs of this mini to the costs of this plan above.
