At some point it went from Vermont - which, being a New Englander myself, I consider Northern New England - to "Southern New England", which I would say is Connecticut or Rhode Island.
Curiously, assuming it's the same car, it is now being listed as a 1960 Goliath. From the little I know about Goliath details, this is most likely a 1959.
Goliath cars were sold in the US. In 1958 - the last year of sales figures I could find - they sold around 3500 cars here. They had over 150 dealers.
