Clint Eastwood's new movie about J Edgar Hoover would be interesting enough without all the Model A's. The segment on the 30's from the Lindberg kidnapping through the Chicago crime wave has many Model A's in it, as the frugal fledgling FBI had to stay within budget with Ford cars. Hoover himself was chauffeured in a 31 slant town sedan.
