As I mentioned in another post, my brother lives there. He bought my late uncle's Pro Street AMX, and took it out there. Aside from Bandimere enforcing every NHRA law to the letter, he has to physically present the car at the DMV before he can get plates. It's sad because it's not really a race car, just a cool street car.... Now, he's balled up with a mismatched VIN due to previous front-end damage, and the CO DMV won't register the car. Here in MD, all you have to do to get Historic plates is present the Bill of Sale, Insurance info, title, and pay the fee (which is pretty lax considering how many "other" laws we have).
If he has the MD title in his name he outta just register the car in SD.
He can do it himself or use a service:
