My grandparents TV in the 1960's was what I still believe to have the best car to ever tow a trailer: a loaded 1968
Monaco with all the heavy-duty parts that were part of the police package. And a high compression 440-4V that averaged 10 mpg towing or solo.
What made for the best series of police cars ever built (until today) was the advantage of Chrysler engineering (see subtopic of same name: 1971 Dodge police cars: Dodge Coronet and Polara
), and this advantage of bulletproof and best performing drive train couple to unitized construction and bigger brakes made one heckuva competent car.
I sold my daily driver 1971 Chrysler a few years ago. It is eye-opening to a neophyte to drive any 1960's competition against a Mopar, the comparison absolutely deflates the proponents of Oldsmobile, Mercury, you-name-it.
Those used muscle cars we 1970's teenagers abused and hopped up were no match for a DODGE Polara Police Pursuit
. The "scariest" moments of the 55-mph years was topping a rise on a highway and seeing one of those T-Rex's idling in the median, with that 108" whip still buttoned down. You might outrun him a few miles, but he had the power, the better chassis, the better stability and the better range to haul you down bodily. Hemi Roadrunner, 6V 427 Corvette, didn't matter.
Radios were for cops who might ought to look for other work. The big Dodge made them redundant.
