Saw a saucer with extreme brightness, spinning rapidy, with windows surrounding the ship, and no sound.

Observed Saucer 1000'overhead.  Lowered to 500' and was spinning very rapidly with no sound at all.  The saucer was brightly lit with a very luninous look to it.  There were windows evenly spaced around the whole ship which lead me to believe it looked like a spinning rooftop restaurant.  Got in my car and quickly drove toward the yatch basin and as I looked in my outside mirror, I saw the ships reflection and it was following me.  As I approached the yatch basin 2 more people standing outside pointed at it and started to run.  The ship was 2000' above us and then disappeared so quickly that it looked like a star in a matter of seconds.
