License plates are tied to specific cars. You have to register your new car with the DMV, they will issue you new plates. If you purchased your car from a dealer they probably already registered the vehicle and are just waiting on the plates.
There's a difference between antique and classic, at least for old cars it is. In some states any car over 25 years old is considered an antique and will qualify for antique license plates. In other states it's 30 years. In some places 30 or 35 years old exempts the vehicle from safety inspections.
