My grandfather sold A's new.He told me that the reason for their survival over others through the scrap drives was mainly two things.1. Gm bodies were wood framed,and when the roof leaked the cars fell apart.With the A's if you screwed a little bit of metal roofing on you could make them last with the minimal amount of wood in most of the cars. 2. Fuel mileage.He said you could pull 16-18 MPG out of a worn A if you were careful,but only 10-12 out of a worn GM or Mopar.So the GM's and Mopars got dropped on Germany of Japan and the A's stayed home working.That 4-8 MPG difference was of huge importance then.A 90 year old man in town tells of hauling Packards,Caddys,Lincolns,etc.to the rail siding by horse teams so as not to use the gas to get them there.People donated cars by the dozen here to the cause.
