Cobra Registration - Arizona

[vegan2]

I'm looking at a Cobra that is registered in California as a 1965 car. Does that mean that Arizona will automatically accept the car as a 1965 and does anyone know what the impact is, e.g. cost of registration (versus a newer "year") and whether or not antique status is available and preferred?

Another way of wording this: is there a real advantage, registration (or any other cost issue) cost wise, to looking at Cobra's with an early year registration? I suspect that there is at least in some states, based on the way some of the for sale ads are written, but I'm not sure.

Any input would be appreciated.
