Automobiles went from being strictly luxury items for the wealthy to a mode of transportation even the middle class could afford in the 1920s, but most cars were still being made for rich folks.
And in the 20s and 30s the decadence of the Art Deco era was reflected in the designs of luxury automobiles like the 1936 Delahaye 135 Competition Court Figoni et Falaschi Coupe (above) or the 1932 Auburn V12 Boattail Speedster.
And while these big and beautiful cars seem bulky and horribly inefficient by today's standards could you imagine the look on your neighbors' faces if they saw a 1925 Rolls Royce Phantom sitting in your driveway! *drool*
