A poster over on GT-R UK forums had his "state legal" R32 GT-R seized by US Department of Homeland Security.
"I just had homeland security come to my house (after owning the car for about a week, (agents said it was just bad timing on my part nothing triggered it i just owned the car at the time)) in Houston, TX and tell me that my gtr was illegally imported and needs to be seized. They said that they are cracking down on all "illegal" skylines in the country and it was part of some big skyline investigation or some crap. I have the seizure warrant if anyone wants proof.
By "illegal" they mean r32's and 34s without DOT bond releases. There is NO WAY for me to get it back as a race car, show car, offroad, etc. The car is not technically significant, prepped for track, etc to qualify for those sections, so i am being forced to export it. Lets not get into the debate about legal versus not legal in this thread. I was just another one of those guys who thought that titled, registered meant legal, but now i know after talking with many head honchos at DOT."
I posted on that thread that I found it odd to get his car seized. His is the first I have heard of.
