Same here, I used to think they were rare as heck bc I never saw any in CT besides BP and one other owner. Now they are popping up more and more. I have seen at least 7 or 8 in the past year with CT tags, even verts. Mostly women driving them though.
I have a feeling that maybe they were once garage queens by the initial owner, and are finally being passed onto other people. It used to be an "Oh My God, Another ZHP" when I saw one on the road to "another nice E46 on the road".
