Perhaps regulations have changed recently, but I have purchased a Vehicle for a foreign non-resident that did not have a CUIT, he did have to register for a CDI, which is similar to the Tax ID number that you get in the USA when you dont have a SSN. The amount of paperwork to purchase/register a vehicle has gotten better (ie less) over the years... its still not as "easy" as in the USA but its not that drastic.
