America is the worst country to be a car enthusiast. All these safety laws regarding importing are complete fucking BULLSHIT. It's just a way to keep you from buying foreign. You can build a fucking car in your garage with questionable safety and drive it on the streets but a foreign car that's been safety tested in it's own country is a no go? Shit, Jay Leno had some car registered federally that would be illegal for everyone else just because he had his buddy Bill Clinton "help" him out.
If you have an illegal car here that's registered, good for you. More power to you.
