amabhy is correct, the only time the Federal vs. California emissions matters is when the car is sold BRAND NEW from the dealer. California compliant cars can be sold brand new in all 50 states, Federal compliant cars can be sold brand new in every state EXCEPT California and New York, however after the initial sale at the OE dealer, both California and Federal compliant cars can be sold/bought/registered in any of the 50 states.
Only California compliant cars can be sold new in Connecticut also. DEEP: LEV II
I had to research this when I bought mine. Since I bought it new and registered it in Michigan (in order to drive it home) and then registered it in CT when I got back home, I was exempt from this standard.
