Being a late built car, it is highly probable that it was built in Flint and went to a dealer somewhere else in the country other than CA and sat on the lot, then someone was looking for a car like that with those options, but it was too late in the year to order a new one, so the dealer in CA tracked one down, got it from another dealer, shipped it to CA, then added the CA emissions air cleaner so it could be sold there.
