I was talking to a friend of mine who scored a Porsche Boxster S for a year with 40% below normal monthly lease rate. Some guy he works with couldn't afford it anymore and he took over the lease with 60% of the monthly payment. The guy still pays the other 40%. What are the legalities of something like this? Where can I find deals like these or are they word-of-mouth kinda thing? What are the risks?
