Thanks Darrin, Harry...
It's a 1/18th scale and it's the American Muscle Authentic's edition from ERTL. These Monte Carlo's come in white, black, silver and burgandy * this color being the hardest to find*. You can find them on ebay but they do bring quite a price, unless you can find one at a reasonable price.
I have the black one also, just need the silver and burgandy one's...
