Can a stolen police cop car still be identified if the tracking devices and cameras are successfully removed?

YES

There are other methods to find the vehicle

VIN

Prior registration

Yes, potentially.

First off, we'll assume that you actually get away with stealing the vehicle in time to remove these i.e. nobody sees you stealing the car, you don't get into a chase with the police, or any of that- which is not likely. Unless you incapacitate the officers (have fun with that), or are very, very lucky, there's not much chance of removing the trackers on site without being seen, and if you try and take the car with the trackers still on, well,that's asking for trouble.

Even then, every car, police or otherwise, has VIN numbers in several locations, and some models have other identifiers. So yes, identifying the vehicle would be easy enough unless you were very thorough in your modifications- and indeed, if you have the resources to completely remake a police care to make it untraceable, makes you wonder why you needed to go out of your way to steal a cop car specifically, given the consequences that could follow. Speaking of which:

In addition to the charges of stealing the car and stealing police property, you might also find yourself charged with assaulting police, evading police, failure to stop, impersonating police (if you were driving a clearly-marked police car before you had the chance to repaint it, that would count), operating a police vehicle without authorisation, evidence tampering, and a whole host of other charges.

Yes, there are tons of ways to still identify the vehicle. Your better off at going to an auction and just purchasing a old police cruiser since it will cost you more scraping the vehicle down and removing all the identifying parts.

The VIN would be the same still.

Not to mention the paint job....

With all that effort, you might as well buy a car and convert it to whatever you want. You could buy one and make it into whatever street-legal version a pseudo-cop car it would be where you are.

Oh, you would need a false VIN then too...

VIN numbers,located in at least 3 places on all vehicles will do it

yes

Yes, of course.
