I haven't received the letter yet either, but here's the BS from the DMV site:
Antique License Plates and Special Plates
Virginia motorists who own antique vehicles should be aware of several changes governing the use of antique license plates.
* Applicants for antique license plates must show evidence of ownership or regular use of another passenger car or motorcycle.
* Applicants must submit notarized certification that their antique vehicle meets safety equipment requirements for the model year in which it was manufactured.
* Fees charged for registration and plate purchase changes from $10 annually to a one-time fee of $50.
Antique plates are available from DMV for vehicles with a model year that is more than 25 years old. New guidelines for these cars were prompted by concerns that many owners were registering older cars as antiques to avoid registration and safety inspection requirements.
Under the new law, if an antique vehicle owner is convicted of operating an antique vehicle determined to be unsafe or not properly equipped, DMV will suspend the owner's registration of the vehicle involved for five years.
