In California, when you buy a car private party or dealer, the selling party must smog the car before they sell it to you. Some private parties will say "car sold as is", so no smog check prior. I would think now buyers will be more adamant for a smog check now.It may take longer than that - consider a person that knows nothing about cars that buys a used car that has been tuned (unbeknownst to them). That's going to be a problem that won't rear its head right away.
But yeah, it will eventually simma down.
