Many policemen out there are “car people” as well…and as long as you are not doing something stupid and are driving safe, they usually will treat you with respect, and in many cases they just want a closer look at your car.
I lost track of how many times I was pulled over in my Superbird, for what turned out to be a “wanted a better look at” type stop. Never cost me anything more than a bit of my time and a small heart condition each time the red lights went on behind me….
