what models were polic cars?

There is a '71 Coronet and a '77 Monaco Royal Brougham (Washington State Patrol only ordered these) in White Center-aka 'Rat City'. They are about 1/2 mile between each other in yards. Anybody in the area can cruise up Delridge and see the Monaco, but the Coronet is behind the house. Passed on a '76 Dart squad for $450 this summer (former Olympia PD car). Know where another is, but the SPD wants to put that one in their museum :salut: . I like cop cars...can you tell?
