This question is better suited for a quick Google search. If you are actually interested in spending $3+ million on an Enzo in the United States, contact your local (or nearest) Ferrari dealer or contact any number of super car dealers near you or throughout the country. There are also a number of exotic vehicle brokers throughout the United States which can set up a transaction on your behalf. You could also contact the major auction houses (RM Sotheby’s, Gooding & Co., Bonhams, Mecum...) and ask them if they could keep you posted on any Enzos making their way to the auction block.
