From South Carolina Code of Laws:

Code 1976 § 56-3-2210. Department of Motor Vehicles may classify certain motor vehicles as antique.

Every motor vehicle as herein defined which is over twenty-five years old, is owned solely as a collector's item and is used for participation in club activities, exhibits, tours, parades, and similar uses, but in no event used for general transportation, may be classified by the Department of Motor Vehicles as an antique motor vehicle.

Code 1976 § 56-3-2220. Issuance of special license plates for antique motor vehicles authorized; duration; fee.

Upon receipt of an application on a form prescribed by the Department of Motor Vehicles, it may issue appropriate designated license plates to owners of antique motor vehicles. Such license plate shall be valid so long as title to such vehicle is vested in the applicant. The fee for the certificate of registration and license plate of any such vehicle shall be ten dollars.

Code 1976 § 56-3-1450. Year of manufacture license plates.

(A) An owner of a motor vehicle that is thirty years old or older, may apply to the department to use a license plate issued by this State in the year corresponding to the model year of the vehicle, if the license plate is legible and serviceable, as determined by the department. If the department determines that the plate is legible and serviceable, the applicant must submit the regular vehicle registration fee contained in Article 5, Chapter 3 of this title, and the special license plate fee required by Section 56-3-2020. The biennial renewal fee for these plates shall be the regular vehicle registration fee contained in Article 5, Chapter 3 of this title, and the special license plate fee required by Section 56-3-2020.

(B) Once the department approves use of the plate and the applicant submits the required fees, the department shall register the plate to the applicant. The department may not register a license plate that has a sequence of numbers, letters, or other characters identical to any other license plate already issued by the department. The applicant may only use the special license plate on the vehicle with which the license plate registration corresponds.

(C) License plates registered pursuant to this section may only be transferred to vehicles of the same model year as the year the license plate was originally issued.

Code 1976 § 56-3-2345. Antique dealer license plates.

(A) Upon application being made and the required fee being paid to the Department of Motor

Vehicles, the department may issue antique dealer license plates to a licensed motor vehicle dealer. The license plates, notwithstanding other provisions of this chapter to the contrary, may be used exclusively on antique motor vehicles owned by, assigned, or loaned for test driving purposes to the dealer when operated on the highways of this State by the dealer, its corporate officers, its employees, or a prospective purchaser of the antique motor vehicle. The use by a prospective purchaser is limited to seven days, and the dealer shall provide the prospective purchaser with a dated demonstration certificate. The certificate must be approved by the department. Antique dealer plates must not be used to operate wreckers or service vehicles in use by the dealer nor to operate vehicles owned by the dealer that are leased or rented by the public. No antique dealer plates may be issued by the department unless the dealer furnishes proof in a form acceptable to the department that he has a retail business license as required by Chapter 36 of Title 12 and has made at least five sales of antique motor vehicles in the twelve months preceding his application for a dealer plate. The sales requirement may be waived by the department if the dealer has been licensed for less than one year. For purposes of this section, the transfer of ownership of an antique motor vehicle between the same individual or corporation more than one time is considered as only one sale. Multiple transfer of antique motor vehicles between licensed dealers for the purpose of meeting eligibility requirements for antique motor vehicle dealer plates is prohibited.

(B) For good cause shown, the department may issue extra plates. If a dealer has been licensed less than one year, the department shall issue a number of license plates based on an estimated number of sales for the coming year. The department may increase or decrease the number of plates issued based on actual sales made.

(C) The cost of each plate is twenty dollars.

(D) For purposes of this section, "antique motor vehicle" means a motor vehicle which is over thirty years old.

Code 1976 § 56-19-485. Designation of vehicles as "wreckage" or "salvage", etc.

Notwithstanding any other provision of law, whenever any motor vehicle which qualifies as "wreckage" or "salvage" is transferred in this State pursuant to Section 56-19-480, whether the vehicle was, immediately before such transfer, titled in this State or in another state, the vehicle shall be designated as "wreckage" or "salvage", as may be applicable, to the extent necessary to inform the transferee of the exact condition of the vehicle. No wrecked or salvaged out-of-state vehicle or South Carolina registered vehicle shall be registered under the laws of this State without such designation, and this designation must be applied to all subsequent transfers of the vehicle.

The provisions of this section apply to transfers of vehicles in all of the circumstances described in Section 56-19-480, whether the vehicle is "totaled", declared a total loss, "junked", or "salvaged".

Notwithstanding the provisions of this section, the owner of a vehicle whose total cost of repair, including all labor and parts, is estimated to be seventy-five percent or more of the fair market value of the vehicle must provide the Department of Motor Vehicles an affidavit from a person who reconstructs or rebuilds a vehicle indicating the cost of repair along with other data the department may prescribe to obtain a certificate of title. The provisions contained in this section do not apply to a motor vehicle that has a fair market value of two thousand dollars or less, or an antique motor vehicle as defined by Section 56-3-2210. A certificate of title issued for a vehicle described in this paragraph must be annotated to indicate the motor vehicle is designated "wreckage" or "salvage" as applicable to the extent necessary to inform the transferee of the exact condition of the vehicle. A wrecked or salvaged out-of-state vehicle or South Carolina registered vehicle may not be registered in this State without this designation,and this designation must be applied to subsequent transfer of the vehicle.
