Absolutely silent UFO hovering over my car.

The color of the object was not known as it was slightly before midnight, when my friend and I spotted this disk hovering over our car. I was driving a 1969 fire engine red convertible, Pontiac Firebird with the convertible top down, I had to stop the car to observe this phenomena. The UFO was round in shape with about a dozen lights surrounding a central fuselage area. I remember looking at the hood on my car, and there were no reflections of the lights from the UFO.
The UFO hovered directly over my car at an altitude of about 75-100 feet, it was absolutely silent. And then it moved to the southwest of my car approximately 100 yards and gained another couple hundred feet in altitude. It stopped and then came back directly over my car for another minute or so. Then all of a sudden it accelerated to the southwest again and totally disappeared.
I called the state police the next morning and the local airport to see if there were any unusual flights in this particular area. Nothing unusual was reported.
