It could very well have been a detective unit. At that time, the detectives drove the same police package Gran Furys as patrol, sans the lights & decals. The inside was set up identically to the marked units, and they had a red spot. At night, during overlap, patrol drove these white unmarked cars as well.

this car has nothing to identify it as a classic squad car.

I was a police officer in Salinas in 1977 & most likely drove this car at one point on patrol. I still live in the Salinas area...if anyone knows where this car is I would love to stop by for a reunion!

As an officer with San Juan Bautista PD in the mid to late 70's, I remember these Grand Fury's Salinas used, as well as San Benito County SO using Green colored Fury's. I drove a 74 all White Dodge Monaco. What a shame to see photos like this. These Fury's were decent patrol vehicles.
