I've always thought that the front end of these cars looked too much like similar vintage Chrysler Cordobas. Not identical, of course, but not that dissimilar, either.
Very similar but the Monte Carlo went to quad stacked rectangular headlights first in 1976. Cordoba was not until 1978. So Chrysler did the copying.
Well remember Ford was one of the first in stacked lights with the ‘58-‘60 Lincoln’s, and the ‘65-‘67 big Ford’s.
