The Model Year registration became effective as of 10-1-09, as an example:

Make: Composite
Year: 1965
Model: Cobra

CT refers to all kit cars/replicas as Composite, the law did not change the Make name, only the Model year.

The 4C's ( CT Council of Car Clubs ) has reported new kit car registration, made after 10-1-09 , have been given the model year of choice. The one example cited was a Porsche. The owner had brought with him the section of the law which established model year registration. The applicant filled out in advance the paperwork with the Model Year of choice.

Not sure if the DMV might require a picture etc of an original to validate the requirement the model year the body most closely resembles.

For CT Composite registrations, exempt from emissions testing, RI ?

Your " Harder to sell " question, with so many states all having different regulations, no easy answer. Might or could be a 1965/66 in one state, but the new state might/could require kit cars/replicas to be the Model year to be the year registered in the new state.

Happened to me when I had a legal title/registration, not a Title company, from one state as a 1965 and CT would not accept , since it was a kit car. Also, might be different regulations in the various states regarding compliance with emissions.
