Can I use the classic car registration loophole for JDM imports?

Many states offer "historic vehicle," "antique," or "classic" registration for cars 25 or more years old, which typically waives smog inspections. This aligns conveniently with the federal 25-year import exemption. Requirements vary — some states limit mileage or require proof the car is used only for exhibitions. Montana has become popular for LLCs that hold vehicle titles without a mileage-based registration, though the legality for out-of-state residents is legally contested.
