Kit cars are treated as vehicles whether they are presented for importation as a fully assembled vehicle, or as an unassembled vehicle in a kit. A kit car does not meet the import requirements for the SOC label, the 17 vin #, or admissibility status. Therefore it is not permitted entry unless it was assembled 15 years ago or longer and the importer can submit proof of age on a registration document. The age of a kit car is determined by the date of assembly rather than the model year of the reproduction or the date of mfg of a donor car.
