at least we don't have crazy state registration offices demanding DOT approved headlights, resulting in skylines sporting Integra headlights to get registration like you guys in Canoodlia
And no we can import any skyline of any age, as long as it meets the power to weight requirement (ie must be a performance car).
nathan, sounds like you just have an illegally modded car which is grabbing their attention (maybe loud BOV?) It's pretty easy to get it back to legal if it's just induction mods. Cover the pod and replace the BOV with a recirc valve and you should be fine.
