Just look at any Hemming's Muscle Machines magazine It contains pictures pf individuals owners cars that have been restored, and those same cars going on the action block.
It lists the average resale value of every make and model by year. The 1964 has the highest average price followed by the '66. The '67 is $10,000 cheaper than the '66 in average price which to me is a measure of how popular it is.
I personally never saw the TV show that featured the 1967 Impala (I don't watch TV other than the news, or drag racing). I used to watch Star Trek, and Babylon 5, and my favorite Star Gate but they have been off the air since forever.
