Is there a vintage / collector´s market in the U.S., for
antique autos made (and originally sold) in South America?
e.g. Would a mind condition 1961 VW Beetle made/sold in 
Brazil be worth anything to an American collector?

Thanks.

depends on the facts if it has original paint, tires, etc. has it been
used or was it a sunday driver?

Thanks for your comment.

It is in all-original, "restored" condition. My concern and the reason
for my question, is that I assume that this car is illegal to drive on
the streets in the U.S. And so I'm wondering if a car that's not street-
legal is desirable to collectors in general.

If someone wants to put it in a museum that would not be a concern,
but I don't think the car museum market is very big.
