Cal. Veh. Code § 507.5

A “remanufactured vehicle” is a vehicle that has been constructed by a licensed remanufacturer and consists of any used or reconditioned integral parts, including, but not limited to, frame, engine, transmission, axles, brakes, or suspension. Remanufactured vehicles may be sold under a distinctive trade name. An existing vehicle which is incidently repaired, restored, or modified by replacing or adding parts or accessories is not a remanufactured vehicle.
