I personally didn't like the front end of 78-79 including the 300 because it made it look like a Ford LTD and T bird of the same era. The 75-77 had a Jaguar look.
Reading the history of the name "Cordoba" it was actually first used by a model of Newport 1970 model. Then they made it its own line in 1975 and was a huge hit.
Wikipedia:
"The car was a success, with over 150,000 units sold in 1975, a sales year that was otherwise dismal for the company. Gauges, except the tachometer, were standard.
[16] For the 1976 model year, sales increased slightly to 165,000. The mildly revised 1977 version also sold well, with just under 140,000 cars. The success of using the Chrysler nameplate strategy is contrasted to the far fewer sales of its similar and somewhat cheaper corporate cousin, the
Dodge Charger SE.
