Restoring a Police Car
Restoring a police car is unlike restoring anything else, for one reason: the things that make it a police car are the things a normal restoration would quietly tidy away.
The drilled holes in the fenders. The extra wiring under the dash. The harsh ride. The odd, unlovely speedometer. A good restorer improves a car. A good police car restorer knows which faults are the point.
What not to improve away
The holes
Drilled spotlight holes in the fenders or A-pillar, and filled roof holes from a light bar or antennas, are the physical evidence that the car did the job. Fill them and you have removed the proof. If the car is going back to police specification they should be kept and reused. If it is going to civilian trim, photograph them thoroughly first, because a future owner will ask.
The wiring
Heavier or spliced looms, switch panel mounts in the transmission tunnel, and cable runs under the dash are all department work rather than factory work — and they are among the most convincing evidence a car can carry. They are also exactly what a tidy rewire eliminates.
The speedometer
The calibrated, certified speedometer was a legal instrument: an officer had to swear to what it read under oath. It is often the last original police-specific item still fitted, and it is worth preserving even if it no longer reads accurately. Replacing it with a civilian unit removes something genuinely rare.
The suspension
Police suspension is harsh, and it was never disguised. Softening it makes the car nicer to drive and less of what it is. That is a legitimate choice — but make it knowingly, and keep the original parts.
The dating problem
This is where careful restorations quietly go wrong, because a part can be correct for the marque and wrong for the year.
The clearest example: a Federal Signal badge on a car restored to 1969 specification is a later part, because the company was Federal Sign & Signal until 1975. The badge is right in every respect except the one that matters. Light bars, beacons and sirens all have datable sequences of their own, and a knowledgeable viewer checks them before anything else.
The practical consequence is that sourcing equipment takes longer than sourcing mechanical parts, and it is worth doing slowly. A car with correct-but-wrong-year equipment reads as a tribute regardless of how genuine the underlying vehicle is.
The order that matters. Value in these cars follows documentation first, correct period equipment second, and originality of the driveline third. A restoration that improves the paint while replacing the driveline has moved the car down that list, not up it.
Livery: the last thing, not the first
Paint is the most visible part of a police car restoration and the least meaningful. It is also the easiest thing to get subtly wrong, because department schemes changed, and a scheme applied to the wrong year of car is the same error as a wrong-year light bar.
If the car is genuine and documented, paint it as its own agency ran it in its own year. If it is a tribute, say so — a well-executed tribute honestly described is a good thing to own, and pretending otherwise only creates a problem for whoever buys it next.
Keep the paperwork with the car
Whatever documentation exists — build sheet, fleet records, ownership chain, photographs of the tag before restoration, photographs of the holes before they were filled — belongs with the car permanently.
Documentation is the single largest component of what these cars are worth, and it is the one part that cannot be rebuilt. A restoration that loses the paperwork has destroyed more value than any amount of bodywork can replace.
Get the details right before you commit to them
The Golden Age covers what each manufacturer’s package actually contained, system by system, so you know what should be under the car before you start replacing it. It also traces the equipment — beacons, bars and sirens — through the era, which is what makes dating them possible.
Sixteen chapters, every claim checked against two independent sources, hedged, or cut, with twenty-one common errors listed openly at the back.

Should I fill the spotlight holes when restoring a police car?
Not if the car is going back to police specification — they are physical evidence that the car did the job, and filling them removes proof. If you are returning the car to civilian trim, photograph them thoroughly first, because a future owner will want to see them.
What is the most commonly missed detail in a police car restoration?
Equipment dating. A part can be correct for the marque and wrong for the year. A Federal Signal badge on a car restored to 1969 specification is a later part, because the company was Federal Sign & Signal until 1975. Light bars, beacons and sirens all have their own datable sequences.
Should I keep the original police suspension?
If you want the car to be what it was, yes. Police suspension is genuinely harsh and softening it makes the car pleasanter to drive, which is a legitimate choice — but keep the original parts, because correct police-specification mechanicals are far harder to find than restorable bodies.
Is it acceptable to build a tribute police car?
Yes, provided it is described as one. Many well-known police cars at shows are tributes and their owners say so openly. The difficulty arises only when a tribute is later sold as a genuine agency vehicle, because the buyer inherits a claim nobody can support.
What adds the most value to a restored police car?
Documentation, ahead of everything else. Then correct period equipment, then originality of the driveline. Paint and livery are the most visible elements and the least significant to value.
