most police cars were "spartan". low trim level, few options, rubber floors.
when the mfgs. started offering uplevel trims with an otherwise police-spec set of mechanicals, we started to see more bling offered in every cop car class including the pursuit rigs (around 1968(?), though it varied by mfgr., AMC was as early as 1965 for example)
the chiefs/captains/supervisors, in some departments, got carpet, power seats, deluxe wheel covers, etc. along with a thumpin' Super Commando/Magnum, big a** brakes, HD-cop spec everything.
fleet owners like WSP really took care of the everyday trooper too with the uplevel trim packages they specified. by the 1980's power windows and other amenities unheard of 20 years earlier were common in police cars and still are today.
so for the Fusies, depends on departmental practice. There is a thread floating around here from 2014 where we thrashed this topic about quite thoroughly and informatively .. lots of good member participation and I learned a LOT
