How to import a classic car from Mexico

Hi, my name is Andrea, I'm from Florence, Italy, and I live in Mexico, I would like to buy classic cars here in Mexico, restore them, and then export to the U.S. for sale.

Does anybody here know what should I need to import a classic car to the U.S.?

Here: CBP Customer Service there's a link regarding the import of classic cars, but it's not working ( Login Template Title ), I only found that "Cars that are more than 25 years old are exempt from EPA and DOT requirements" and "EPA will permit the importation of a nonconforming vehicle only if it qualifies for exclusion or an exemption, or is imported by an independent commercial importer (ICI), who is a current holder of a valid EPA certificate of conformity. The ICI importing the vehicle has to clear the goods through CBP, not the vehicle owner."

Hope someone can help me in finding the best way to sell a classic car in the U.S., thanks
