Most 60-70:s US cars was sold new trough dealers but loads of cars was also brought in to military personnel during the Vietnam war era. US had army bases in Thailand also after the war so i guess thats why you can find 2 door muscle cars and not only 4 door sedans.
Its hard to trace the history of a car but the rumor has it that my Challenger was brought in to a guy who was stationed her several years.
Anyway, took me 15 years to gather my little collection so it is rare to find nice cars.
Didnt Korea have US army bases as well?
Ive been trying to find something like that in Korea...nothing but Kias, Dawoos and hyundis here
