An antique car as defined by the Antique Automobile Club of America
must be at least 25 years of age or older and is currently functioning
and restored to comply with the manufacturers original specifications.
Over the years the definition has been refined to include several
classifications of vehicles. For example, in 1953 a new Class 18 -
'Antique Cars with four-wheel brakes' was added to the definition.
There have been many changes in classes from time to time, but the
common thread is that vehicles have to be restored, in good running
condition and in excess of 25 years of age.
