I don't have the specific details, but I think you're very close. Locked for you to find the model name.
Thanks for the lock. I've been unable to find any additional information on this car, however. I'll keep looking, but feel free to unlock the thread in the meantime so others can try as well.
It's not from South America.
In that case, allow me to expand my scope: Latin America?
Well, It's a 1982 Camaro.
Your source may have identified it as an '82 model, but this car is clearly a 2nd-gen Camaro. GM introduced the 3rd-gen F-bodies (Camaro/Firebird) for MY82, available for sale in the U.S. as of December 1981.
