I know this is concerning the old Police cars, but the last few comments were concerning the sound of the Police cars under full throttle, so...
I live about a block off the last intersection going out of town on a State highway with an empty parking lot between my place and the highway. That highway intersects a city by pass about a mile out of town. As such, much of the emergency response vehicles heading out of town are under wide open throttle as they go past my place.

Without a doubt, those modern Hemi power Police vehicles sound as good and maybe better then the squad cars of the past. Though they sound as good, and probably run better, they sure don't have the class of the old squad cars. Gene
