Instead of a marriage contract perhaps something more like a short term lease with a guaranteed buy back program?
"My lease is up on my Peruvian next month, I was thinking about getting a Brazilian this time."
"How about getting a trusty ol` Filipina? Not the most economical, but they always get good reliability ratings!"
"Oh everyone has a Filipina, I want something that makes more of a personal statement, besides I had one of those once, had nothing but problems with it!"
The only question I have is how could a leaser install an odometer so as to charge a fee for "overmilage"?
