1965 Mexican Spec Plymouth Valiant Acapulco

This car is very , very cool!
Every time I see this front end on a sedan, it makes me wonder why Mopar didn't offer a Formula S in this configuration, including a convertible. One case where they completely missed a golden opportunity. I keep thinking about a 4-speed with an aluminum performance version of the slant 6. What a great car that could have been!!
On that point I am going to guess they didn't want to dilute the specialness of the Barracuda.

The Barracuda was also sold here but with a slant 6 so they were basically the same car.
