Those old cars are not as collectible because Ford and other auto manufacturers nearly doubled their production of cars in 1915-1916. And in doing so, these old cars lost some of the previous quality found in cars in 1914 and before.
Go! Just keep going; never stopping for a rest.All the day I keep on dodging bill collectors with a zest.
Summer clothes we wore all winter, Now 'tis spring, they're nearly through;Once I paid my life insurance, now it's more than I can do.
Little ones are nearly barefoot, pantry shelves are empty now.I have chopped wood most all winter, before this year I knew not how.
Ne'er before in my existence, has the tank on my machineEver starved, and froze the family, keeping 'er filled with gasoline.
(Bill Davis, 1915)
