Where can I buy a Mercedes Benz 450sl 1980 from Germany that ships to thee United States of America?

The price, shipping, insurance, and cost of importation, would probably make it a bad deal. That is if it met 1980 U.S. standards. A few types of exotic cars can be imported under a special program, but are severly limited as to how many miles they can be driven per year; but I don't believe a 450SL would be one of them.
