My suggestion: Introducing fake number plates to the black market
How it will work?
You go to the black market and purchase the fake number plate just like an illegal gun. And with the number plate you bought, you can place it on your desirable car.
The number plate will last like for an hour or so . Allowing you to commit crimes without the cops being able to trace the vehicle back to you.
Why I suggested?
It allows you to commit crimes anonymously without the cops identifying you. I have had a cop in the past issue me a warrant by just getting details from the car from a robbery.
And also , it's more reliable than using the locals car that can disappear any moment.
