What could be found as evidence that a car was once a police car? My grandpa always said his/my 30 fordor was once a police car.
The only evidence that I have is it came with a police head, and a number of holes in my firewall that if a police car, could have been a horn. It also has two aftermarket amber fog lights mounted.
And at least one bullet hole.
Hence his Jodhpur riding breeches......Motorcycles reigned supreme back in that era.
