Look what I was told about registering a kit car in Georgia

I live in metro Atlanta where emissions testing is required for all automobiles and apparently the rules are changing again for kit cars. The governing body in GA over emissions testing is the EPD (GA version of EPA) and their rep said by state law any kit car regardless of what appears on the title (i.e. even if your title said 66 cobra)is treated and must pass the emissions requirements of a new car built in the year the kit car was first registered. This applies to me buying someones kit car from out of state regardless of what year the kit car title describes the car. The rep said not only will cats be required on the car, but Federal law requires OBD computer controls (during the emissions testing the equipment is connected to the OBD computer)and the state is trying to decide this week if they must force all kit cars to comply! That is not a misprint! I was told that adapting an OBD would be expensive. Metro Atlanta (essentially 1/3 of GA)is in a non-attainment zone requiring all cars to be tested.
Anyone else in GA ..what did you hear? Any suggestions? How expensive is OBD? I wonder if other states are considering the same type of actions?
