I used to own a 2004 Black Mercury Marauder and it happened all the time. Our Marauder club was very active and when we traveled together we were routinely mistaken for a group of FBI or LEOs. Nice when traffic gets out of your way but not so nice when they slow below the speed limit. I was behind a co-worker on the way into work the other day and he thought I was a LEO. Not at all why I bought either car, just love the performance and style.
