Live in California's central valley where we get some ridiculous thick fog in the winter. Fog lamps are pretty much essential equipment. But for some odd reason the fog lamp option is coupled with the 16" wheel upgrade, which isn't available with the 1.4 liter engine. Seems odd at best. And since you can get 17s with the 1.4 on the Z model, makes even less sense. What gives, Chevy?
