Several years back, the "people" of California demanded some good old smog-check justice, feeling that in general they were getting ripped off by unscrupulous smog stations. California adopted a "test only" system and had separate stations where only a test could be performed, and no repairs. If you fail then you go a different station to get repairs made and test again. Smog cks have run around $30-40 for a long time. If you get chosen by DMV for a test only, it's three or four times as much. If your car can't pass after repairs there's a convoluted system to petition the state to allow you to keep your car and drive it. Another swing and a miss for the land of fruits and nuts.
