Default Question about California Emissions

I'm looking to buy a C6 and was running through the CarFax. Says the car was purchased in WV, but then taken to California. It failed emissions 3 times and then suddenly passed it.

There is additional equipment for controls there, correct? What parts would have been installed to meet these controls?

Here is the VIN: 1G1YY24U955117180

Does it say why it failed? I took my C6 from Massachusetts to CA and it passed OK, not sure if they're different.

Emissions testing in CA has different rules for a car you buy from out of state. It also must be retested again after 2 years.

Although there is a California Emissions RPO code, all U.S. C6s should have identical engines and emissions equipment.

My '06 coupe does NOT have the California Emissions RPO (I purchased it out-of-state) but it DOES have the California Emissions sticker under the hood, and that's what the CA DMV cares about. They don't give a damn about RPOs.

Other owners have said that their C6s do NOT have the California Emissions sticker, so at some point GM may have left the sticker off cars without the RPO.

I doubt they had to install anything that wasn't there to begin with in order to get the car to pass. They probably had to put stuff back that had been removed (such as the cats) or remove aftermarket stuff that failed visual (non CARB-exempted) or caused the car to fail at the tailpipe.

Here's the problem: smog tests are expensive, and if you fail big-time you get a "gross polluter" blemish on the car's title. That car shouldn't have rolled into a smog station ONCE with equipment that would cause it to fail, let alone THREE times.
