I don't get how that isn't basically just a lease? Except that the buyer gets something that looks like a call option that sounds like it's nearly guaranteed to be below expected (normal, maybe not in rough times) value? Mainly because I've never seen a lease where the dealer doesn't ask you if you want to buy it.
